Abstract
This paper presents the design of a CPW-Fed circularly polarized metamaterial (MTM) antenna using short ended configuration. The proposed antenna consists of a Composite Right/Left Handed (CRLH) Transmission Line (TL) unit cell and double hexagonal split ring resonator (SRR). The antenna offers compact size with overall dimensions of 0.17 λ 0 x 0.24 λ 0 x 0.013 λ 0 . The antenna shows triple band characteristics with the first band centered at 2.61 GHz, second band centered at 4.12 GHz and third band centered at 6.24 GHz with an impedance bandwidth of 6.54%, 6.61% and 34.20% respectively. The proposed antenna shows circular polarization in the first band and linear polarization in other two bands. The antenna shows peak gain of 2.4 dBi, 3.38 dBi and 4.26 dBi for the three bands respectively.
