摘要

本文设计了一种新型差分微带贴片天线(DMPA)，用于近程f波段MIMO雷达的透镜天线馈电。DMPA由一对耦合线差分馈电。天线通过差分阻抗匹配网络连接到模块的差分输出，从而消除了射频前端对平衡器的需求。仿真天线增益约为8dbi，带宽(S11 <;- 10db)在125- 137ghz之间。初步实验测量显示了使用0.13 μm SiGe:C BiCMOS技术的发送/接收模块，使用线键连接到片外dmpa的混合连接。传输链路评估结果表明，在DMPA近场增加10 mm半径的3D打印聚酰胺透镜，增益增加约15 dBi。

Differential microstrip patch antenna as feeder of a hyper-hemispherical lens for F-band MIMO radars

In this paper, a novel differential microstrip patch antenna (DMPA) is designed and used to feed a lens antenna for short range F-band MIMO radars. The DMPA is fed differentially by a pair of coupled lines. The antenna is connected via a differential impedance matching network to the differential output of the modules, eliminating this way the need of a balun in the RF frontend. The simulated antenna gain is about 8 dBi and bandwidth (S11 <; -10 dB) is between 125-137 GHz. Preliminary experimental measurements are shown using Transmit/Receive modules in 0.13 μm SiGe:C BiCMOS technology, hybrid connected using wirebonding to off chip DMPAs. It is shown by the transmission link evaluation that the gain is increased by about 15 dBi adding a 10 mm radius 3D printed polyamide lens in the near field of the DMPA.
