A new compact microstrip antenna with enhanced gain is presented in this paper.The design parameters, resonance characteristics, radiation pattern and directivity of this antenna are evaluated.A performance comparison between the conventional microstrip antenna and the novel microstrip antenna is given.It is shown that the gain of this novel microstrip antenna reaches to 10.908dB, the back lobe is-13.442dB, and the resonant frequency is reduced by 820MHz.The enhanced gain makes the proposed antenna applicable for some special wireless communication environment, especially for array applications in base stations.
