CPW - Fed Square and Semi - Circular Patch Antenna for UWB, 4G & 5G Applications

Coplanar waveguide fed design of modified patch antenna is implemented by using combinations of square patch with a semi-circular shape patch which is surrounded by parallel rectangle semi-circular ring shape ground plane is proposed for ultra-wide band response for 4G & 5G applications (FR1 band). A study by varying patch dimensions is performed to optimize the patch configuration. The proposed design yields an ultra-wide response from 3.54 GHz and exceeds towards 12 GHz (greater than 8.5 GHz of bandwidth). Antenna provides radiation pattern which is broadside over entire bandwidth with more than 4 dBi as peak broadside gain.
