本文介绍了一种基于复合右/左手（composite right/left-handed，CRLH）超材料的新型高增益的有源漏波天线(leaky-wave antenna，LWA)。这种天线工作在边射，由无源CRLH漏波部分与放大器相互连接,重新组成一种在辐射过程中逐步增大功率泄漏的结构,从而提高天线的有效口径进而提高其增益。通过放大器的准单向特性而导致的匹配再生功能,增益还可以进一步得到提高。-This paper presents a composite based on the right / left (composite right/left- handed. CRLH) - The new high-gain active leaky wave antennas (leaky-wave antenna. LWA). This antenna work on the side-by - Passive CRLH missed part amplifier connected, A re-formed in the course of radiation gradually increase the power structure of the leak, thereby enhancing the effective antenna aperture consequently enhance their gains. By the quasi-one-way amplifier characteristics which led to the regeneration of the matching function, gain can be further improved.
