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.
A single layer, single feed compact slotted patch antenna suitable for dual-band operations is thoroughly simulated in this paper. Patch antenna is basically a low cost, light weight, medium gain and narrowband antenna and suited for short-range microwave application such as a feeding element for other antennas and in research institutes as a reference antenna, it can also be used at output of signal conducting circuit for receiving signals from MEMS. By loading properly arranged slots on a rectangular microstrip patch, dual frequency and broadband operations of a single feed rectangular patch is achieved to increase bandwidth performance of the antenna. The impedance bandwidths of 562.85 MHz with return loss -28.64 dB and 1.17 GHz with return loss -43.40 dB are obtained in the proposed design. And simulated antenna size has been reduced by 59.07% with an increased frequency ratio when compared to a conventional microstrip patch antenna. The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication and make it suitable for the applications in microwave communication system.
