Abstract

This paper presents the design of composite right/left handed transmission line (CRLH TL) wideband metamaterial antenna. The bandwidth enhancement was achieved by replacing horizontal ohms shape slot with series horizontal slot. A comprehensive parametric analysis using Computer Simulation Technology CST software is carried out by varying the position of the slot Ln to determine the effectiveness of the concept and find the right position of the slot for obtaining the wideband. From the simulation work, it was found that the impedance bandwidth covered from 2.2 GHz to 4.6 GHz which is equivalent to 75% fractional bandwidth. The antenna has a compact size of 30 by 16.80 mm2. It has three different resonating bands at 2.6 GHz, 3.4 GHz and 4.5 GHz within the range with realised peak gain of 2.39 dBi, 2.41 dBi, and 3.22 dBi respectively and average efficiency of 95%.
