摘要
提出了一种双极化256元集成相控阵天线，工作频率范围覆盖5G NR N257频段（即26.5-29.5 GHz）。通过采用具有成本效益的集成相控阵技术，多功能电路可以实现高密度配置，从而在不牺牲性能的情况下减少系统占用空间。采用一种高隔离双极化天线的设计方法来增强交叉极化抑制。所提出的相控阵支持±$\pm$ 40°$40^\circ$和±$\pm$ 60°$60^\circ$在方位角和分别为高程平面。双极化天线典型有效各向同性辐射功率（EIRP）大于61 dBm， 5G NR 400-MHz 64-QAM调制(EVM <；$<$ 5.6% $\%$)。
A 26.5–29.5 GHz 256-Element Dual-Polarized Integrated Phased Array With 61-dBm EIRP and 400-MHz 64-QAM Modulation
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).
