A compact CPW-fed metamaterial antenna for high efficiency and wideband applications
In this paper a compact planar CPW-fed metamaterial antenna with closed ring resonator (CRR) has been proposed. It is observed that by employing CRR into the structure an extra band is found at 2.17 GHz (n = -1 mode) and therefore electrical size of the antenna is decreased significantly. CPW- feed is introduced to enhance the bandwidth and radiation efficiency of proposed antenna. This antenna is operated at 2.15 - 2.19 GHz and 3.2 - 5.25 GHz, at the center frequency 4.23 GHz. It achieves peak antenna gain of 2.97 dB and radiation efficiency upto 97%. In addition to that proposed antenna shows consistent radiation patterns throughout the bandwidth.
