摘　　要：设计了一种应用于成像的二维天线平面阵列,利用串行馈电的方式,减小了大型阵列因较长馈线而带来的损耗,保证了天线增益,采用四分之一阻抗变换线进行加权,在带宽内天线在两个主平面副瓣在均低于-20dB,达到了设计要求,实现了微带阵列天线的低副瓣、高增益、宽频带的指标。A two-dimensional antenna array is designed for imaging.The use of serial feed is used to reduce the loss of large arrays due to the longer feeder,which ensures the antenna gain and uses a quarter of the impedance The conversion line is weighted,and the antenna in the bandwidth is lower than-20dB in the two main plane sidelobes,which meets the design requirements,and achieves the low sidelobe,high gain and wide band of microstrip antenna.

关 键 词：串馈微带阵列天线 低副瓣 宽频带
