Abstract
This invited talk will provide a review of recent development and future trends in ultra-wideband dual-polarized phased array antennas using tightly coupled arrays techniques. Such antennas are promising for future multi-function systems integrating communications, sensing and imaging onboard smart terminals (airplane, UAV, cars, satellites, trains, ships…) in 6G and beyond. The past decades saw rapid development of wireless communications, radar and imaging systems using more and more frequency bands, together with more and more antennas and arrays. As antenna is a critical component of any wireless systems, it is necessary to develop one single ultra-wideband dual-polarized phased array capable of receiving and sending multiple beams over an ultra-wideband frequency range for multiple systems e.g. communications, sensing and imaging. Such an antenna could replace numerous separate antennas and arrays, hence leading to significant reduction in size, mass and complexity of antenna systems onboard smart terminals.
During recent decades, many research programs on this were carried out. For example, Advanced Multifunction Radio Frequency Concept (AMRFC) Program, funded by US Office of Naval Research, aimed to demonstrate the integration of numerous types of shipboard radio frequency functions including radar, wireless communications, and electronic warfare utilizing a common set of wideband array antennas, signal and data processing, signal generation, and display hardware. Recently, the “Advanced Antenna Technology for a Smart World” Project, funded by Hong Kong Research Grant Council, was launched. One of objectives of this project is to develop compact-size ultra-wideband phased arrays for integrated communications, sensing and imaging
