基于一维复合左/右手传输线的电控漏波天线

Electronically Controlled Leaky-Wave Antenna Based on the One-Dimensional Composited Left/Right Handed Transmission Line

一维复合左/右手传输线微带漏波天线具有基模工作模式,且馈电简单,并具有频率扫描的特性,但不利于实际应用。文章提出一种新型结构,通过加入变容二极管,实现了在固定频点上波束可控,更适于实际应用。

A microstrip leaky-wave antenna based on one-dimensional composited left/right handed transmission line possesses dominant-mode, simple feed and frequency-scanned properties, but it isn＇t fit for practical use. Through adding varactors, a new structure is introduced and it realizes controllable wave-beam of fixed frequency which is better for practical use.
