Abstract

In view of the low gain and single frequency operation of common microstrip antenna, a novel dual-band microstrip antenna which is fed by microstrip line is proposed in this paper. Using software HFSS to simulate and optimize it, the antenna can work at two bands which are 3.25-3.35GHz and 4.31-4.42GHz.The total bandwidth is 0.21GHz, while the gain is only 2.1dB.In order to further improve the gain and the bandwidth, a dual-band microstrip antenna with coplanar waveguide (CPW) fed is designed, the current distribution of the patch is changed by etching U-shaped and V-shaped slots. The return loss and the radiation efficiency are improved by adopting the CPW feeding structure. The simulation results show that the antenna can work at the two bands of 4.25-4.35GHz and 4.64-4.8GHz simultaneously. The maximum gain is 5.1dB. The performance parameters of the optimized antenna are improved compared with those of the original antenna. It can meet the application requirements of dual- band microstrip antenna.
