Abstract

In this paper, a novel ultra-wideband (UWB) miniature antenna based on the composite right-left handed transmission line (CRLH-TL) structure with enhancement gain is proposed and investigated. With CRLH metamaterial (MTM) technology embedded, the proposed UWB and miniature antenna is presented with best in bandwidth, size, efficiency and radiation patterns. To realize characteristics of the antenna, the printed -shaped gaps into the rectangular radiation patches are used. This antenna is constructed of the two unit cells, also presented antenna is designed from 2.25 GHz to 4.7 GHz which corresponding to 70.5% bandwidth. The overall size of the presented antenna is 10.8mm×6.9mm×0.8mm or 0.09λ0× 0.05λ0 × 0.006λ0 at the operating frequency f = 2.5 GHz (where λ0 is free space wavelength). The radiation peak gain and the maximum efficiency which occurs at 4.6 GHz, are 3.96dBi and 63.6%, respectively.
