摘　　要：微带天线具有体积小、重量轻、易于集成在非平面物体表面等特点,被广泛应用于卫星通信、雷达和导弹等领域。设计了一款中心频率工作在3.5 GHz的2×2微带相控阵天线,采用圆形贴片作为天线单元结构,通过微带线馈电。用仿真软件CST对该天线进行仿真及分析,其结果表明,在工作频段均满足天线增益G≥11.3 dB,回波损耗S 11<-10 dB。同时,该天线可在E平面上实现最大±16°的定向波束扫描。该天线阵元数目少、增益高、体积小,更便于集成在曲面等物体表面,适用于通信中Wi-Fi频段。The microstrip antenna is widely used in satellite communication,radar,and missile due to its small size,light weight,and easily integration on non-planar surfaces.This paper designs a 2×2 microstrip phased array antenna with a center frequency of 3.5 GHz.The antenna uses a circular patch element as the driven unit and is fed by microstrip lines.The antenna is designed and simulated by CST software.Testing results demonstrate that the gain of the antenna is greater than 11.3 dB and return loss S 11 is lower than-10 dB across the operating frequency band.Moreover,the antenna can achieve azimuth±16°beam scanning beam scanning in E-plane.The antenna has the advantage of fewer antenna elements,high gain,and small size performance.This antenna is easier to integrate on curved surfaces and is suitable for Wi-Fi frequency bands in communications.
