Abstract
In this paper, a wideband microstrip antenna loaded with split ring resonators (SRRs) has been designed. The proposed antenna consists of three parts: the square patch, the ground and the suspended substrate loaded with SRRs. The bandwidth of the antenna is enlarged by capacitively coupled feed and its resonant frequency can be lowered due to the influence of the loaded SRRs. Simulation results show that the antenna has a 700-MHz bandwidth from 1.70 GHz to 2.40 GHz and the gain is higher than 5.5 dB within the bandwidth. By loading arrays of SRRs, a size reduction of 5.7% is achieved with good radiation features.
