摘　　要：介绍1种X波段余割平方赋形平面微带阵列天线设计,该天线采用交叉极化抑制度高的非辐射边馈电双层微带贴片天线作为辐射单元;馈电网络采用低损耗悬置微带线(SSL)并结合“联合应用DFP和BFGS公式的变尺度算法”,实现了俯仰方向余割平方波束。基于项目需求设计加工了1套16×4单元阵列天线,测试结果表明,该阵列天线在10.2-10.8GHz的设计频带内回波损耗小于-10dB,带内交叉极化电平优于-35dB,带内增益大于22dBi,波束覆盖满足项目指标要求。A design of X-band cosecant conformed planar microstrip antenna is introduced.The antenna uses a non-radiating edge-fed double-layer microstrip patch antenna with high cross-polarization suppression as radiation element.The feeder network adopts low-loss suspended microstrip line combined with the variable-scale algorithm of DFP and BFGS formulas to realize the pitch direction cosecant pattern.Based on project requirements,a set of 16 × 4 cell array antennas has been designed and manufactured.The test results show that the return loss of the array antenna is less than -10 dB in the design of 10.2?10.8 GHz,the intra band cross-polarization level is better than -35 dB,the intra band gain is more than 22 dBi,beam coverage meets project target requirements.
