摘　　要：设计1种双频双极化层叠式微带天线,该天线采用双层贴片及短路加载等措施有效展宽了天线频带宽度。基于项目需求设计、加工了1套天线,测试结果表明,该天线在L频段(1.65?1.75 GHz),电压驻波比VSWR≤2,相对阻抗带宽约6%,带内增益大于8.2dBi;在C频段(3.40-4.20 GHz),电压驻波比VSWR≤2,相对阻抗带宽约21%,带内增益大于7.5 dBi.In this paper,a dual-band dual polarization cascaded microstrip antenna is designed.The bandwidth of the antenna is effectively broadened by using double-layer patches and short circuit loading.A set of antenna is designed and manufactured according to the project requirement.The test results show that the relative impedance bandwidth of the antenna is about 6%,the voltage standing wave ratio less than 2,and the in-band gain is more than 8.2 dBi in L-band(1.65?1.75 GHz);In the C band(3.40-4.20 GHz),the relative impedance bandwidth of the antenna is about 21%,and the in-band gain is more than 7.5 dBi.
