Wideband Filtering Patch Antenna Design for cmWave 6G Applications

This paper proposes a dual polarized planar patch antenna design for 6G applications in the cmWave frequency band. The design is based on low cost, low loss multilayer RF laminate enabling 92% of radiation efficiency. In addition, a wide impedance bandwidth of 21% is achieved using differential Lprobe feeds. By implementing additional shorting pins to the feed, the antenna also exhibits good out-of-band rejection from 24.25 to 27.5 GHz, which is currently deployed for mmWave wireless communication systems.
