摘要：
In this work, a compact and low-profile metamaterial-based antenna has been developed. The antenna bandwidth is improved by employing square ring-shaped defects in the ground plane. The circularly polarized (CP) antenna has been implemented by two pairs of radiators. CP characteristics have been obtained by placing two radiators for X-polarized wave and two radiators for Y-polarized wave. Each radiator is designed with epsilon negative transmission line (ENG-TL) to generate zeroth order resonance (ZOR). The performance of the proposed antenna is analyzed in terms of S-parameter bandwidth, axial ratio bandwidth (ARBW), gain, radiation efficiency and VSWR (Voltage Standing Wave Ratio) using Computer Simulation Technology (CST) design studio. Simulated results show that the antenna obtains a gain of 4.98 dBic, which is improved by 0.62 dBic compared to the structure without square ring-shaped defected ground structure. Also, the simulated operating bandwidth and axial ratio bandwidth (ARBW) of our proposed antenna improve to 698.6 MHz and 231.5 MHz.
