چکیده
This paper presents rectangular, fractal and proximity coupled patch antennas on a two layer substrate with the air-gap. The antennas have been designed on εr = 2.2, h = 1.5748 mm with initial dimension 49 x 41.01 mm of simple rectangular patch. The simulated resonant frequency of rectangular patch is 2.42 GHz. The fractal antenna and the Fractal antenna with Layered Stack shows the multi band behavior at frequencies ranging from1. 9397 GHZ to 10.06 GHZ and 4.92 GHZ to 9.56 GHZ respectively The bandwidth of fractal patch has been improved with 0.8 mm air gap in two layered fractal patch in stack with better gain than rectangular patch .The radiation pattern of fractal antenna is as similar to rectangular patch antenna but cross polarization is better in fractal patch.
