摘要：

We present a method of reducing the size of antennas that is based oil composite right/left-handed (CRLH) transmission lilies (TL) which use a magneto-dielectric material (MDM). The CRLH-TL antenna consists of two mushroom structures, each composed of a metal patch connected to the ground plane by a via. To achieve high permeability ill the antenna, an MDM is constructed by integrating split ring resonators into ordinary dielectric material. Antennas with and without MDM were fabricated and measured. inserting the MDM decreased the antenna's resonant frequencies by 10.8% at the - 1st order mode and by 11.3% at the zeroth-order mode. At the zeroth-order mode, the antenna resonated at 1.88 GHz with a bandwidth of 0.48% and had a monopolar radiation pattern, with gain of 0.534 dBi and efficiency of 51.7%.
