Abstract :
A single-layer, single-feed, metallic cylindrical cavity backed concentric annular-ring microstrip patch antenna (ARMSA) with circular patch has been investigated using a High Frequency Structure Simulator (HFSS) software. Variations in return loss with frequency for different values of air-gap height, radius of circular patch and radiation pattern of proposed antenna have been analyzed. The patch miniaturization of about 8.97% and bandwidth enhancement about 20% have been achieved using cavity backed ARMSA and concentric circular patch antenna as parasitic element.
