A single layer monopole hexagonal patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting three unequal slots which are the combinations of one circle and two irregular rectangular slots from the conventional microstrip patch antenna. It is shown that the simulated results are in acceptable agreement. More importantly, it is also shown that the differentially-driven microstrip antenna has higher gain of simulated 3.36 dBi at 9.61GHz and -0.43 dBi at 13.57GHz and beam width of simulated 162.08 0 at 9.61GHz and 53.45 0 at 13.57GHz of the single-ended microstrip antenna. Compared to a conventional microstrip patch antenna, simulated antenna size has been reduced by 50.80% with an increased frequency ratio.
