Type: article

Abstract: ABSTRACT A dual‐polarized 256‐element integrated phased‐array antenna is presented, with an operating frequency range covering the 5G NR N257 band (i.e., 26.5–29.5 GHz). By adopting an integrated phased array technology with cost‐effective fabrication, multifunctional circuits can be implemented in high‐density configurations, thereby reducing system footprint without sacrificing performance. A design methodology for the dual‐polarized antennas with high isolation is employed to enhance the cross‐polarization suppression. The proposed phased array supports scanning angles of and in the azimuth and elevation planes, respectively. The typical effective isotropic radiated power (EIRP) of the dual‐polarized antenna is greater than 61 dBm with the 5G NR 400‐MHz 64‐QAM modulation (EVM 5.6).
