MIM CRLH Series Mode Zeroth Order Resonant Antenna (ZORA) implemented in LTCC Technology

Abstract

A metal-insulator-metal (MIM) composite right/left- handed (CRLH) series mode zeroth order resonant antenna (ZORA) implemented in LTCC technology is presented and demonstrated to exhibit excellent efficiency (71%) and co-to-cross polarization performances, in addition to a high gain (10 dB) provided by its large electrical size of 2 lambda <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> . Due to its versatile characteristics, high performances and capability to attain at low cost high directivities, conventionally available only with standard arrays, this antenna may find various applications in future.
