Miniaturized MIM CRLH transmission line structure and application to backfire-to-endfire leaky-wave antenna

Abstract

A novel miniaturized metal-insulator-metal (MIM) capacitor composite right/left-handed (CRLH) transmission line architecture has been proposed and demonstrated to exhibit an almost twofold reduction factor in size in comparison with a previously published interdigital CRLH structure. The MIM CRLH transmission line has been demonstrated as a backfire-to-endfire leaky-wave antenna with excellent scanning performance. The proposed antenna is to be fabricated in LTCC.
