Increasing the demand of wireless communication systems, the micro strip patch antennas becomes very popular because of its low cast, light weight, easy to feed and attractive radiation characteristics. In spite of various advantages it also suffers with some draw backs such as narrow band width, low gain and surface waves. By the introduction of new (HIS) High Impedance Surface as reflecting ground plane in micro strip patch antenna design, there is an improvement in radiation characteristics such as band width, gain and directivity. In current paper comparative analysis of results obtained in conventional design and 2D HIS design were presented.
