Abstract: 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.
