| 摘 要： | 介绍了一种工作在基模状态下的微带漏波天线.这种天线基于传输线结构,其传播常数由负值增加到正值,显现出一种随频率增加而具有的由后向辐射变为前向辐射的特性.通过实验,验证了基于一维特异材料的微带漏波天线的这种特性.

| Abstract: | This paper presents a dominant-mode microstrip leaky-wave antenna, This antenna is a transmission line structure with propagation constant increasing from negative to positive values, providing the backward to forward scanning capability as frequency is increasing. The characteristics and performances of the antenna are demonstrated by measurement results, |
