Twice -Band Microstrip Hexagonal Slotted Patch Antenna for Microwave Communication

A single layer, single feed compact slotted patch antenna is thoroughly simulated in this paper. Resonant f requency has been reduced drastically by cutting three equal slots which are same hexagonal structure at the upper right, upper left and lower left corner 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 3.24 dBi at 9.91 GHz and 0.14 dBi at 13.61 GHz and beamwidth of simulated 163.19 0 at 9.91 GHz and 122.10 0 at 13.61 GHz of the single-ended microstrip antenna. Simulated antenna size has been reduced by 48.11% with an increased frequency ratio when compared to a Conventional microstrip patch antenna.
