摘　　要：针对5G毫米波通信,研制了一种双极化有源相控阵天线模组。厚度为2 mm的多层PCB正面印制阵列天线,在其背面集成多通道波束成形芯片,通过中间层实现天线与芯片的互连以及供电、控制等。测试结果表明,研制的板状4×4双极化相控阵模组在E面和H面均实现了不小于±40度的波束扫描范围(不大于3 dB的电平下降)和低于-18 dB的归一化交叉极化电平,在24~27.5 GHz的频率范围内实现了V极化和H极化分别为42.6~45.7 dBm和43.5~46.1 dBm的等效全向辐射功率(EIRP)。A dual-polarized active phased array antenna module is presented for 5G millimeter-wave communications.The array antennas and multi-channel beamforming chips are printed and implemented on the top and bottom layers of the multilayer PCB(2 mm thickness),respectively.Besides the interconnection of the antenna and chip,power supply and digital control are realized within the middle layers of the multilayer PCB.The measured results show that the beam-scanning range larger than±40 degrees(power level declines smaller than 3 dB)and normalized cross-polarization level smaller than-18 dB are both achieved in E-and H-planes.Besides 42.6-45.7 dBm and 43.5-46.1 dBm transmitting equivalent isotropically radiated powers(EIRPs)for V polarization and H polarization are realized respectively.
