ABSTRACT

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 applications. Phones, cars and planes are connected to the network, connectivity is everywhere. This also means that our terminals, objects, devices need to be compatible with many wireless standards and bands requiring different antenna types and functions. Multi-antenna or wideband antenna systems were a hot topic in the past, 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 the utilization of 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 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.
