Dual-Polarized End-Fire MM-Wave Mobile Terminal Antennas for 5G and Beyond: An Overview

With the rapid advancement of 5G mobile communication, the mm-wave band has become a focus of technological innovation for mobile terminal antennas. Our group is dedicated to overcoming the technical problems in the design of mm-wave mobile terminal antennas, particularly in terms of small ground clearance, wide bandwidth, single layer and integrated package. Through systemic research and exploration on the implementation of end-fire dual polarization, a series of high-performance mm-wave terminal antenna solutions have been developed. These works are categorized into two types, low-profile dual-polarized end-fire antennas and high-gain dual-polarized end-fire antennas.
