摘　　要：提出了一种5G毫米波有源阵列封装天线。该阵列由8×16个微带天线单元组成,通过耦合式差分馈电,天线实现了宽带匹配和方向图高度对称特性。通过对天线与芯片进行合理布局,减小了芯片射频端口到天线子阵的馈电线损,提高了有源阵列天线的整体效率。测试结果表明,该阵列天线在工作频段为24.25~27.5 GHz的等效全向辐射功率(Equivalent Isotropic Radiated Power, EIRP)大于60 dBm,并且阵列波束扫描至±30°、±60°时的增益下降分别不超过0.6 dB、4.1 dB,具有良好的宽角度波束扫描特性。This paper presents a 5 G millimeter-wave active array antenna-in-package. The active array consists of 8×16 microstrip antenna elements. By designing a coupled differential feed structure, the antenna subarray achieves broadband matching and highly symmetrical pattern. By rationally arranging the antenna and the chip as a whole, the feeder loss from the RF port of the chip to the antenna sub-array is reduced, and the overall efficiency of the active array antenna is improved. The test results show that the equivalent isotropic radiated power(EIRP) of the array antenna is greater than 60 dBm in the operating frequency range of 24.25-27.5 GHz, and the gain decrease of the array antenna when the beam scanning to ±30 ° and ±60 ° is less than 0.6 dB and 4.1 dB respectively, which has good wide angle scanning characteristics.
