Abstract

In this study the techniques for enhancement of impedance bandwidth of the microstrip patch antenna were analyzed. The techniques of defected patch, defected ground structure and parasitic patches were implemented to improve bandwidth of the antenna. Size of the substrate/ground plane of the proposed antenna was 17x6.4 mm2. The impedance bandwidth of the proposed antenna was 5.51 GHz and a return loss of 26.01dB was obtained at the center frequency of 15.9 GHz. This antenna can be implemented for satellite communications in Ku- Band.
