Abstract:

Patch antenna now become famous due their compact design high bandwidth and satisfactory gain and directivity. Patch antenna are using in the world now in enormous application where the demands of low space like in panels of satellite transponder and in mobile phones etc the paper present the new design of rectangular microstrip patch antenna for wifi communication. In the paper two antennas are designed first one is Rectangular microstrip patch antenna for 5.8 GHz communication. And second one is Rectangular microstrip patch antenna with step DGS strip antenna for wifi, property of both the antenna like simulated design, return loss, directivity, Radiation Pattern and bandwidth are discussed. This work shows that bandwidth of Antenna in RMPA with step DGS is increased about 71.3% which is very good enough for wifi communication, return losses of designed antenna is also decreased by 83.40%, Gain of the proposed antenna increases to 4.88dB from 4.749dB and Rectangular Microstrip Patch Antenna with step DGS and slot in the patch also reduces the size of antenna which is always a basic need of Patch antenna design system.
