We have proposed diversity antenna which consists of two billhook shaped patch elements along with rectangular slot inserted in it and a narrow semi-circular shape on the ground plane. Ultra-wideband (UWB) diversity antenna elements are placed orthogonal to each other to obtain high isolation, also achieve the polarization and pattern diversity. We have calculated the patch size of diversity antenna is 33×18mm in compactness condition. In this paper, the diversity antenna is implemented, fabricated and its parameters are evaluated by CST Studio. The proposed technique of UWBMIMO (Multiple Input Multiple Output) antenna achieved larger bandwidth, low mutual coupling and envelope correlation coefficient (ECC) over the UWB frequency band. For diversity antenna, we have observed diversity performance factors like diversity gain, capacity loss, and ECC. With the help of these parameters, we have shown improvement in the channel capacity. Through our simulation and experimental results, it is observed that our new proposed technique is better than existing methods.
