Abstract :
In this paper a novel design for miniaturization of patch antenna is presented. The proposed design for the miniaturized wide band patch antenna consists of hybrid techniques of H-shaped slot on the patch and defected ground structure. Defected ground structure is formed by cutting a combination of U and L-shaped slots. Patch and the ground plane are shorted for the further size reduction. These practices increase the current distribution path accompanied by increase in electrical length of the antenna. To validate the design a reference patch antenna is designed and its performance is compared with the proposed antenna. The designed antenna is 86% smaller than the conventional patch antenna. The miniaturized antenna has gain in the range of 4dBi to 5dBi while impedance bandwidth is in the range of 105MHz to 1700MHz. This form of compact wide band antenna is appropriate for numerous wireless communication systems like cell phone, Laptop and Hyperlane.
