In this paper, simple techniques are been proposed and investigated successfully to overcome the basic limitations of gain, bandwidth for a microstrip antenna and mutual coupling for a microstrip antenna array. A meandered E shape patch antenna with a air cavity is proposed to enhance gain and bandwidth. To reduce mutual coupling an Electromagnetic band gap structure has been proposed. Coax feed has been used for excitation. The meandered patch provides band width enhancement and the air cavity along with a thick aluminum ground plane combindly provided gain enhancement. E shaped patch has been formed by considering a basic rectangular patch and by etching slots at the edge of the patch. The simulated results show a bandwidth of 89MHz ranging from 1.30GHz to 1.39GHz with a maximum gain of 8.37dB at the operating frequency of 1.35GHz. The antenna has been designed over a RT Duroid 5880 substrate with a dielectric constant of 2.2 and thickness of 62mil. Antenna Design and simulation studies are carried out in Ansys HFSS software.Keywords
