低副瓣边馈微带天线阵列设计

摘要

Microstrip antenna array with high gain and low - side lobe is required in many applications. Through the theoretical study on comer - fed square patch array with coplanar feed. A side - fed Ku band monopulse microstrip antenna array with - 19. 5dB side - lobe has been realized and measured. The results indicate validity of this method for design of high gain and monopulse antenna.%在实际应用中要求微带天线具备高增益、低副瓣、波束控制等特性.基于角馈方形微带贴片阵列天线的理论分析,采用中心短路、边缘馈电的方式设计了低副瓣ku波段单脉冲微带平面天线阵列.经测试所设计的10×10单元单脉冲微带天线阵的副瓣电平达到了- 19.5dB.结果证明该设计方法对高增益单脉冲天线设计是有效可行的.
