目前,微波天线已经不能满足各类飞行器对天线的发展要求,而微带天线具有重量轻、体积小、易于共形的特点成为了研究热点.针对这一问题,提出了一种中心频率4.3 GHz、带宽200 MHz、2×2的高增益宽带微带天线的设计方法,并给出设计参数进行了HFSS软件仿真分析.仿真结果表明:在4.2~4.4 GHz频带范围内驻波比小于2,最大增益12.9 dB,半功率波束宽度为53°,具有良好的方向性,满足飞行器天线的设计要求.%At present, microwave antenna could hardly meet the requirements of various aircrafts for antenna development, and microstrip antennas become the focus of research for their light weight, small size and easy conforming. To solve this problem, the design method of high gain broadband microstrip antenna with center frequency of 4.3 GHz, bandwidth of 200 MHz and 2 * 2 is proposed, and the design parameters are analyzed with HFSS software. The simulation results indicate that in the 4.2~4.4 GHz band, the resident Bobbi is less than 2, the maximum gain 12.9 dB, and the half power beam width 53 degrees, and this proposed design has fairly good directivity and could meet the design requirements of aircraft antenna.
