This is the first report on novel mushroom-type electromagnetic band gap (EBG) structures, consisting of fractal periodic elements, used for enhancing the gain of microstrip patch antennas. Using CST Microwave studio the performance of rectangular patch antenna has been examined on proposed fractal EBG substrates. It is found that fractal EBGs are more effective in suppressing surface wave thus resulting in higher gain. The gain of rectangular patch has been improved from 6.88 to 10.67 dBi.

A wandered probe-fed rectangular microstrip patch antenna (RMPA) with rectangular slots on a finite ground plane with dielectric material substrate (4.4) is proposed in this paper. The proposed antenna finite ground plane dimension is only 18mm x 21mm. The simulated result shows two distinct resonant frequencies at 4.5 and 9.5 GHz. A 10-dB wide-impedance bandwidth of 1000 MHz and 4100 MHz ranging from 3.8-4.8 GHz and 5.9–10 GHz is achieved. The proposed antennas have achieved wider bandwidth (51.3%) with reasonable gain (4 dBi).

The microstrip patch antenna is used in various communication applications including cellular phones, satellites, missiles, and radars, due to its several attractive features such as small size and weight, low cost, and easy fabrication. The microstrip patch antenna consists of a top radiating patch, a bottom ground plane, and a dielectric substrate in between. The patch can have different shapes, the rectangular patch being the most commonly used. In practice, the microstrip antenna suffers from narrow bandwidth and low gain efficiency.
