Abstract: Modern telecommunication systems require miniature antennas with multiband characteristics that support multiple wireless applications. This paper presents a pentagon shaped microstrip patch antenna that works at 7.5GHz with a return loss of -43.48dB. The antenna has been designed on 1.59 mm FR-4 substrate with dielectric constant of 4.4 and loss tangent of 0.02. The pentagon shaped microstrip patch antenna has been modified into a dual band and a triple band antenna by applying fractal shape and frequency reconfiguring the antenna geometry. Proposed antenna finds applications for defense and secure communication, C band (4 GHz to 8 GHz) and X band (8 GHz to 12 GHz) applications where antenna can be used for satellite communication and RADAR applications. Proposed antenna has been designed using IE3D and results are analyzed in terms of gain, return loss, directivity and bandwidth.
