Abstract
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 a U- shaped slot fed by coaxial feeding technique. The proposal antennas designed, simulated and optimized using Ansoft HFSS Vs 15. 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 mechanisms. The results showed that the U-Shaped slot microstrip antennas efficiently operated at 2.4Ghz and 4.6Ghz.
