| 1. | The directivity coefficient of the phased array antenna has been generalized and discussed . according to the formulations of microstrip antenna design theory , planar and cylindrical microstrip patch cell has been analyzed . we can conclude that the cylindrical microstrip patch cell has the performance of high gain , low thickness , high resonant frequency , uniform directivity diagram , and easy fabrication on missile body , so it is a good choice 本文根据微带天线设计理论,分析了平面和柱面两种微带贴片单元,其中柱面微带贴片单元增益高、厚度小、谐振频率高、方向图均匀,且较易加工制作在弹体上,适合在相控阵天线中做共形辐射单元。 |
