Professor, Texas Tech University, Lubbock, TX 79409, USA


By sensing various life activities with microwave signals, portable radar sensors with state-of-the-art front-end and measurement algorithms have great potential to improve healthcare, transportation, and human-machine interface. This presentation will first provide an overview on linear smart radar sensors powered by advanced digital/RF beamforming, multiple-input and multiple-output (MIMO), synthetic aperture radar (SAR), inverse synthetic-aperture radar (ISAR), and deep learning. A few examples based on interferometry, Doppler, frequency-shift keying (FSK), and frequency-modulated continuous-wave (FMCW) modes at 5.8 GHz, 24 GHz, and 120 GHz will be discussed. Then, the mechanism and applications of nonlinear radar sensing technologies will be reported, with a focus on in-band third-order intermodulation measurement for enhanced target identification and parameter extraction. Case studies at this exciting human-microwave frontier will be given on physiological signal sensing, non-contact human-computer interface, driving behavior recognition, human tracking, and anomaly detection.

As smart radar sensors become ubiquitous in many areas of modern life, measures to enhance their security against malicious attacks are of paramount importance. This part of the talk will discuss possible ways of attacks to radar sensors based on spoofing and jamming. Then technologies that mitigate potential attacks will be unveiled to make smart radar sensors more secure and trustworthy. Finally, this talk will conclude with future industrial and academic R&D outlooks for microwave radar sensors.

Highly Sensitive Microwave Sensors for Measuring Intrinsic and Physical Properties

Abhishek Kumar Jha

Associate Editor, IEEE Sensors Journal • IEEE Access || Faculty of RF & Microwaves @ IIT India • GUT Poland || MTT-4


Electromagnetic waves feature superior properties that allow microwave sensors to be more accurate, more sensitive, significantly lighter and smaller in size than their counterparts. In this talk, several microwave sensors will be discussed that can measure the intrinsic properties of matter, e.g., the permittivity and permeability; and can detect the physical quantities, e.g., angular rotation, direction of motion and proximity. These microwave sensors offer measurement of the intrinsic properties at single frequency using resonant technique as well as in the wideband of microwave frequency using transmission and reflection technique. The talk will start with the recent advances in waveguide-based microwave sensors that will address the special class of epsilon-near-zero sensors too. Afterwards, several resonant and non-resonant microwave planar sensors will be discussed, where the mue-near-zero sensor will be introduced, and an innovative arrangement will be discussed that is helpful in converting a wired sensor into the wireless. Later, the planar sensor that can measure two crucial parameters in the automation industry—the angular rotation and the proximity, and offers the user-specific wide frequency operating band selection will be discussed. Finally, a modified design will be presented that can detect the direction of rotation using the asymmetry principle. Using the error analysis, it will be shown that a technique based on phase-change measurements is superior to those based on magnitude measurements alone.

GaN MMIC High Power Amplifiers for K-Band Satellite Payload

Paolo Colantonio

Università di Roma Tor Vergata, Dipartimento di Ingegneria Elettronica


This contribution presents the activities carried out towards the realization of a high-power solid state power amplifier, based on Gallium Nitride (GaN) technology, targeting more than 125W of output power in the frequency range 17.3- 20.2 GHz, conceived for the next generation K-band Very High Throughput Satellites (vHTS). For this purpose, specific Monolithic Microwave Integrated Circuits (MMICs) Power Amplifiers (PAs) were developed on a commercially available 100 nm gate length GaN on Silicon (GaN-Si) process (OMMIC process D01GH). The design was carried out considering space reliability constraints on electrical parameters and accounting for the spacecraft temperature limits, which are extremely challenging for this technology, to keep the junction temperature of all devices below 160 °C in the worst-case condition (i.e., maximum environmental temperature of 85 °C). The final MMIC, based on a three-stage architecture, demonstrates on wafer and in pulsed condition to achieve a minimum output power and power added efficiency (PAE) of 10W (40dBm) and 35% (with a peak of 45%) in the full Ka-band satellite downlink, i.e., from 17.3 GHz to 20.2 GHz. The packaged version demonstrates in continuous wave (CW) conditions an output power larger than 39.5dBm with a PAE better than 30%. Moreover, long-term (24h) CW test at saturated output power has shown almost negligible performance degradation, thus providing confidence in the robustness of the selected GaN-Si technology.

Challenges in RF & mm-Wave Packaging for Radar and Communication Systems

Maciej Wojnowski

Lead Principal Engineer, Head of RF Package Simulation & Characterization

Infineon Technologies AG, Munich, Germany


System-in-package (SiP) is a major trend in integration of microelectronic systems to tackle the increasing needs for more functionality into a smaller volume. SiP leads to heterogeneous integration of integrated circuits along with sensors, microelectromechanical components, passive devices, filters and antennas. Another important trend in packaging is the continuing move toward higher frequencies. 5G high-speed wireless communication, mm-wave radar for autonomous driving and high-resolution mm-wave environment sensing and imaging are just a few examples of applications for future markets. In this talk, we present the latest developments in packaging technologies for mm-wave radar and communication systems. We demonstrate the system integration capabilities of the embedded wafer level ball grid array (eWLB) technology. After introduction of low-loss transmission lines and high-quality planar inductors in thin-film redistribution layers (RDL), we present chip-package-board transitions without external matching networks optimized for use in the 60/70/80 GHz bands. We present the concepts of antenna integration in eWLB and show examples of different antenna structures. To demonstrate the system-in-package integration capabilities of eWLB, we show 60 GHz and 77 GHz eWLB transceiver modules with integrated antennas. The use of vertical interconnections and double-sided RDL extend the integration capabilities to the third dimension. We present ways of realizing vertical interconnections in eWLB using through encapsulate vias (TEV) and novel embedded Z lines (EZL) technology. We show examples of vertical interconnections, embedded passives, RF transitions and 3D antennas realized using the TEV and EZL technology. Finally, we present the concept of substrate integrated waveguide (SIW) for eWLB. To combine advantages of planar circuits with rectangular waveguides we present a novel, compact and low-loss transition from chip to SIW in eWLB and to standard WR10 rectangular waveguide.

Correlating mmWave Permittivity Measurement Tools with an Introduction to Intel’s Metrology Capability Analysis

Michael J. Hill

Assembly and Test Technology Development, Intel Corporation, Chandler, Arizona, USA


To create the advanced 3D stacked package technology used in today’s high-performance microprocessors, Intel relies on a wide array of measurement techniques spanning many technical disciplines. For example, high speed interconnects are often characterized by insertion loss and characteristic impedance which intern are controlled by more fundamental properties like copper conductivity, surface roughness, and the permittivity and loss tangent of the dielectric materials used.  In order to ensure that measurements collected on these important quantities are reliable, robust and reproducible, Intel performs a study called a Metrology Capability Analysis (MCA) on each key metrology.  This process, which others may know as a Gauge Repeatability and Reproducibility study, is a critical part of improving a lab’s ability to collect meaningful data and is a core requirement at Intel.  These studies, which may at first appear onerous and time consuming to perform are in fact very straightforward and provide great insight and improvement opportunities for even the simplest of measurement techniques. 

In this talk an overview of the MCA process used at Intel will be presented along with results from recent efforts to correlate Split Post Dielectric Resonator (SPDR), Split Cavity Resonator (SCR) and Fabry Perot Open Resonator measurements (FPOR). These correlation efforts, which begin with robust MCAs for each metrology, span 5 GHz to 110 GHz and utilize a high purity, ultra-low loss, fused silica prototype reference sample.  This material sample is a proof-of-concept artifact developed as part of an International Electronics Manufacturing Initiative (iNEMI) collaboration effort to create mmWave traceable permittivity reference materials. A brief introduction to that effort will also be provided.

Hill is a Principal Engineer at Intel Corporation in Chandler, Arizona.  He has been with the Electrical Core Competency group since 2002.  His work includes the development of new tools and techniques to allow precise characterization of substrate electrical performance metrics spanning power delivery, highspeed I/O and RF applications.   Much of his recent work has focused on metrologies for characterizing high speed integrated voltage regulators.  In addition to his work in Power Delivery, Michael is also responsible for developing characterization methods for package material sets spanning DC to 110GHz, and methods for characterizing mmWave package integrated antennas.   Michael is a senior member of the IEEE, has authored more than 30 peer reviewed publications and holds 10 patents.  He received B.S., M.S. and Ph.D. degrees in Electrical Engineering from the University of Arizona.  Michael can be reached by email at:

Tunable RF filters: A Step Towards Efficient Spectrum Access & Multi-standard Communications

Dimitra Psychogiou

Professor at University College Cork & Tyndall National Institute


Future wireless communications and emerging services including e-Health, Internet-from-Space and autonomous transport, will be critically dependent on secure and sustainable connectivity.  However, connectivity will depend highly on the availability of electromagnetic spectrum which has become a scarce resource. To utilize the spectrum efficiently, disruptive technology innovations are required including dynamic access, operability at higher frequencies (e.g., mmWaves) and using the same frequency for transmit and receive, e.g., full-duplex. However, current RF transceiver technologies aren’t able to support these functionalities due the high complexity of the RF hardware and the lack of adaptive RF components.

This talk will provide an overview of emerging RF filtering technologies as key enabling elements for efficient spectrum utilization and low SWaP-C RF systems. Specifically, the talk will focus on new RF design methods, RF tuning techniques and integration concepts that facilitate the realization of RF filters with multiple levels of transfer function adaptivity (bandwidth, center frequency, type), multi-band operability and multi-octave spectrum sensing. New RF design paradigms that enable RF filters with co-located RF signal processing actions (e.g., filtering and amplification or matching) will be presented as a way to miniaturize the RF front-end size and improve its efficiency. Furthermore, the talk will demonstrate the fundamentals of introducing non-reciprocity within an RF filtering device with the purpose of realizing truly-full duplex RF systems.
