“…By introducing defects or slots in the ground plane, size reduction up to eight times is achieved but with lower efficiency, increased back lobe level and narrow bandwidth [10,11]. Metamaterials such as ENG, MNG or DNG inspired antennas provide high degree of miniaturization with limited bandwidth, low efficiency and complex geometry [12][13][14][15][16][17].…”

Abstract-A compact 2 × 1 multiple input multiple output (MIMO) antenna system is designed to operate in the LTE band 40 (2.3-2.4) GHz. The proposed antenna consists of two circular patches fed using microstrip line. The antenna was initially designed to resonate at 5 GHz. Size reduction of 55.17% compared to conventional patch antenna is obtained after the inclusion of circular complementary split ring resonator (CSRR) in the ground plane. The resonating frequency was shifted to 2.34 GHz, thereby the board size is compact (50 × 25 × 1.6 mm 3 ). The designed antenna covers a bandwidth of 2.3 to 2.374 GHz with a maximum return loss of −27 dB at 2.34 GHz and isolation of −33.5 dB between the ports. The simulated correlation coefficient is approximately zero, and the total active reflection coefficient is 0.142 at the resonating frequency which are within the acceptable limits. The realized gain for the antenna is −8.9 dB.

Abstract-A conductor backed coplanar waveguide (CPW) fed multiband antenna inspired by CSRR MTM is presented. The shorting of ground in CPW feed and conductor backed arrangement extend the area of ground plane. The proposed antenna consists of rectangular monopole with Complementary Split Ring Resonator (CSRR) engraved in the extended ground plane. The prototype antenna is designed, fabricated and measured. CSRR characteristics are also analyzed. Simulated and measured results of the antenna are in good agreement with each other and are discussed. The proposed antenna can be used for WiMAX, WLAN and RADAR applications at 3.4 GHz, 5.16 GHz and 9.5 GHz, respectively.

In this paper, an electromagnetic metamaterial patch antenna is designed and simulated for cognitive radio applications, as cognitive radio communication is anticipated to be a new technology which utilizes all the bands of radio spectrum. This work uses a complementary split ring resonator between the patch and the ground plane for the purpose of size miniaturization. The proposed antenna system is capable of operating in the frequency range of about 2 to 5 GHz. This wide-band design makes it viable for wide spectrum with 80 percentage effective frequency being covered in the designed band. The desired patch antenna has been simulated using Advanced System Design (ADS) simulator. The simulated results are proved to be good in agreement with cognitive radio application.
