Microstrip Patch Antennas have been used extensively in wireless communication systems due to its advantages of being low profile and cost effective but the antenna suffers from the limitation of low bandwidth. Feeding technique is one of the criteria to be chosen while designing microstrip patch antenna. The paper presents various designs to enhance bandwidth for KU band 12 GHz to 14.5 GHz. Simple microstrip line feed and aperture coupled feed are two techniques which are used to design the antenna, their comparison is done for bandwidth enhancement. Further, analysis and results based on various shapes of patches and height of substrate is also presented.

Abstract


Microstrip Patch Antennas have been used extensively in wireless communication systems due to its advantages of being low profile and cost effective but the antenna suffers from the limitation of low bandwidth. Feeding technique is one of the criteria to be chosen while designing microstrip patch antenna. The paper presents various designs to enhance bandwidth for KU band 12 GHz to 14.5 GHz. Simple microstrip line feed and aperture coupled feed are two techniques which are used to design the antenna, their comparison is done for bandwidth enhancement. Further, analysis and results based on various shapes of patches and height of substrate is also presented.
