摘要

介绍了一种周期性加载c型槽的微带漏波天线。均匀半宽(HW)微带LWAs (HW- mlwas)工作在单波段，辐射的主波束只在正向扫描。所提出的天线工作在两个频段，主波束可以在前进和后退方向通过扫频控制。天线- 10db反射带宽分别为4.2 ~ 4.9 GHz和8.23 ~ 8.8 GHz。当扫描频率为4.2 ~ 5 GHz和7.85 ~ 8.9 GHz时，天线的波束扫描范围分别为22°~ 59°和-76°~ -18°。

A dual-band half-width microstrip leaky-wave antenna for beam scanning in the forward and backward directions

A microstrip leaky-wave antenna (LWA) loaded periodically with C-shaped slots is described. Uniform half-width (HW) microstrip LWAs (HW-MLWAs) operate in a single band and radiate a main beam that scans only in the forward direction. The proposed antenna operates in two frequency bands and the main beam can be steered in both the forward and backward directions by sweeping the frequency. The -10 dB reflection bandwidths of the antenna are 4.2 to 4.9 GHz and 8.23 to 8.8 GHz. The beam scanning ranges of the antenna are 22° to 59° and -76° to -18° when the frequency is swept from 4.2 to 5 GHz and 7.85 to 8.9 GHz, respectively.
