摘　　要：设计了一种用于卫星导航通信的多频圆极化共口径天线阵列,包含3种不同形式的天线,分别为S频段宽带微带天线阵列、北斗S频段交叉偶极子天线阵列和北斗B2b/L双频微带天线。通过对天线阵列的整体优化,3种形式的天线在阵列中均具备良好的工作带宽、轴比以及辐射增益。该多频共口径天线阵列结构紧凑,布局新颖,缩小了天线阵列的体积,优化了天线阵列的空间利用率,实现了多模式的卫星导航通信功能,同时满足了S频段和北斗S频段低仰角通信和抗干扰需求。A multi-frequency circularly polarized common-aperture antenna array for satellite navigation and communication is designed in this paper.The antenna array consists of S-band broadband microstrip antenna array,BDS S-band cross dipole antenna array and BDS B2b/L dual-band microstrip antenna.The three types of antennas in the array have good performance in working bandwidth,axial ratio and radiation gain through the overall optimization.The multi-frequency common-aperture antenna array has a compact structure and a novel layout,which reduces the size of the antenna array,optimizes the space utilization of the antenna array,and realizes the multi-mode satellite navigation communication function.At the same time,it meets the low-elevation communication and anti-interference requirements of the S-band and BDS S-band.
