摘要
采用新型平面微带型和差网络实现了Ku波段单脉冲天线阵列的小型化设计。使用ADS优化设计了一种结构紧凑的"十"字形和差网络,并且使用参数加载等方法,在HFSS中仿真出一个8×8的微带矩形贴片天线阵列作为收/发天线,和差网络和微带天线阵列组成单脉冲天线阵。8×8天线阵列、和差网络和馈电系统在同一平面上,所以此天线阵列与传统单脉冲阵列相比体积更小,结构更紧凑,对该天线阵列进行了研制和测试,测试结果符合设计要求。
A Ku band compact single layer monopulse microstrip patch antenna array has been designed. A cross shaped sum-difference network is constituted by microstrip ramose coupler with compact structure and calculated by ADS,while the 8 × 8 rectangular patchs, which is optimized by HFSS on basis of the method of parameter load and so on, form the transmiting/receiving antenna. Sum-difference network and microstip antenna array form a monopulse antenna array. The array,monopulse comparator and the feed network are placed on the same layer. Compared with tradition monopulse antenna array, this antenna array is smaller and compacter. The monopulse microstrip antenna array has been manufactured and tested, the results are in agreement with the design requirements.
