【摘要】 本文对一种准行波微带天线进行了改进,显著提高天线性能。这种方法采取在准行波微带天线各贴片单元上开双H槽和加装两个短路探针,实现了在天线增益基本保持不变、带宽变宽、电压驻波比变小的效果。而且,在天线主要工作方向上雷达散射截面得到明显缩减,进一步改善了天线的隐身性能。更多还原

【Abstract】 In this paper, the performance of a quasi-traveling wave microstrip antenna has been improved significantly by adaptation. The main point of this method is to cut two H-shape slots and install two short-circuit pins in each microstrip unit of the antenna, which expands the bandwidth, lowers VSWR, reduces the RCS significantly in main working direction, and remains the gain of the antenna unchanged at the same time.更多还原
