摘要
针对小型化毫米波雷达对大探测范围及远距离探测的需求,提出了一种Ka波段串并联混合馈电的微带阵列天线。天线阵列采用模块化设计,通过采用遗传算法优化调整子阵列的相对位置控制波束宽度及增益。仿真及加工实测得到天线在中心频率36 GHz的E、H面波束宽度为28°、15°,最大增益15 dBi,测试与仿真结果基本符合,表明该天线阵列适用于小型毫米波雷达。
Aiming at the needs of miniaturized millimeter wave radar for large detection range and long-distance detection,a Ka-band series-parallel hybrid-fed microstrip array antenna is proposed.The antenna array adopts a modular design,and the beam width and gain are controlled by using genetic algorithms to optimize and adjust the relative position of the sub-array.Simulation and processing measurements show that the E and H plane beam widths of the antenna at the center frequency of 36 GHz are 28°,15°,and the maximum gain is 15 dBi.The test and simulation results are basically consistent,indicating that the antenna array is suitable for small millimeter wave radars.
