A CPW-Fed Structure Shaped Substrate Wideband Microstrip Antenna for Wireless Applications

Abstract A structure shaped substrate wideband microstrip patch antenna fed by coplanar waveguide (CPW) is proposed for wireless applications. Structure shaped substrate is produced by cutting the rectangle shape substrate in the form of a semicircular disc. The radiating patch of proposed antenna is taken in the form of U-shape. The ground plane is extended towards both sides of radiator for reducing the size of the antenna. The proposed antenna is simulated by Ansoft's High Frequency Structure Simulator (HFSS). A good agreement is observed between simulated and measured results. The prototyp...
