In some applications it is required to have dual band characteristics instead of single band. This characteristic can be obtained by embedding a U-slot in the patch and hence the radiating patch includes a pair of step-slots. In this paper, we propose a dual-band microstrip patch antenna with u-shaped slot fed by coaxial feeding technique. The proposed antenna is designed, simulated and optimized using Ansoft HFSS Vs 13. The simulation results are presented in terms of return loss, VSWR, input impedance, Gain and radiation pattern. The dimensions are optimized to achieve the exact operating frequencies using resonating frequency control mechanism. The results showed that the U-shaped slot microstrip antenna is efficiently operated at 2.4 GHZ and 4.6 GHZ resonant frequencies for WLAN applications.
