The Dawn of Multi-Function, Multi-Standard Shared Aperture Antenna Systems
Nowadays, we have wireless connectivity with almost everything around us. We are connected to our home appliances, to our offices, to our healthcare providers among many other services and online streaming services. Our cars are connected to the network, connectivity is everywhere. This also means there is a large magnitude of wireless standards and bands that antenna systems within our devices and objects need to cover and be compatible with. Multi-antenna or wideband antenna systems were a hot topic in the past few years, but to cover the large frequency band differences between 4G (sub 6-GHz) and 5G millimeter wave (24, 28 and 38 GHz) bands, researchers have started exploring utilizing the same aperture to host multi-standard antenna systems to save space and costs. The term shared aperture, or antenna-in-antenna (AiA) has become a new topic with a wide spectrum of applications in future wireless systems and devices.
In this talk, we will discuss the principles and methods of shared aperture antenna systems, and the concept of AiA with several detailed examples and design methods from recent literature. We will discuss the advantages of disadvantages of such systems from practical and performance aspects. In addition, we will touch upon some recent techniques of such shared aperture antenna systems with different technologies by introducing the concepts of Encapsulated Dielectric Resonator Antennas (EDRAs), shared slot multi-band antenna elements, as well as Connected Antenna Arrays (CAA) based shared slot shared aperture antenna systems.

The Dawn of Multi-Function, Multi-Standard Shared Aperture Antenna Systems
Biography:
Mohammad S. Sharawi is an affiliate Full-Professor of Electrical and Computer Engineering at the University of Washington, USA, and a Principal/Lead engineer with Blue Origin, USA, working on cutting edge communication systems for space applications. He was a tenured Full Professor of Electrical Engineering at Polytechnique Montréal, Montréal, Québec, Canada, between 2019-2023. Prof. Sharawi was with King Fahd University of Petroleum and Minerals (KFUPM), Saudi Arabia, between 2009-2018. He founded and directed the Integrated Multi-Application Antenna Group (IMAAG) and the Antennas and Microwave Structure Design Laboratory (AMSDL). He was a visiting Professor at the University of Calgary, Canada, and Oakland University, USA, in 2013, 2014 and 2023.
Prof. Sharawi’s areas of research include Multiband Printed Multiple-Input-Multiple-Output (MIMO) Antenna systems, Reconfigurable and Active integrated Antennas, Applied Electromagnetics, Millimeter-wave MIMO antennas and Integrated 4G/5G antennas for various applications, Dielectric Antennas, and on package antennas. He has more than 400 papers published in refereed journals and international conferences, 11 book chapters, and three books entitled “Printed MIMO Antenna Engineering,” 2014, “Design and Applications of Active Integrated Antennas,” 2018, and “MIMO Antenna Systems for 5G and Beyond”, 2024. Prof. Sharawi has 28 issued/granted and 8 pending patents in the United States Patent Office (USPO). He is serving/served as Area and Associate Editor for IEEE AWPL, IEEE OJAP, MOTL, IET-MAP and Frontiers. He served on the Technical and organizational program committees of several international conferences (EuCAP, APS, IMWS-5G, APCAP, iWAT). Prof. Sharawi is a member of the IEEE Member benefits committee, and the person managing the APS Student travel grant. He served as the EuRAAP delegate for north America. He is a Fellow-IEEE and Fellow-IET. He is currently serving as the IEEE Seattle AP/MTT/ED joint chapter Co-Chair.
