摘要：
A compact microstrip rectangular patch antenna with defeated ground structures (DGSs) is proposed. The DGS with a better performance is chosen so that the reduction in the size of antenna can be achieved. In order to eliminate the negative impact of DGS, a small portion of this patch is truncated so as to acquire a better gain and return loss. This paper elaborate on the mechanism of miniaturization in mathematics and physics respectively and the mathematical model of a single C-shaped ring is obtained. By optimizing these parameters, the size of the antenna can he reduced to 55.58% of the original size while the return loss of the antenna can reach to 37.10 dB. The measurement results indicate that the performance of the antenna can match well with the simulation results.
