Abstract: A reconfigurable asymmetric patch antenna with arced corners loaded with a rectangular slot and a T slot on the partial ground used for UWB and Ku band applications. The discussion is carried out into three segments. In the first segment, the design of patch antenna proposed asymmetric arcs at the corner, two side slits, and one slot in the middle of the patch while a T-slot integrated on the partial ground plane. This presented antenna covers an impedance bandwidth ranging from 3.0 GHz to 16.2GHz with a fractional amount of 132%. It is found that a wide band of 3.0 GHz to 10.7 GHz is achieved by using a T-slot on the partial ground plane with a normal rectangular patch while 10.8 GHz to 16.2 GHz is attained by using two corners arcs with two small slits on the patch. The experimental result shows good agreement of 3-dB axial ratio bandwidth and radiation characteristics with the simulated result of the proposed antenna. The second segment proposes an extracted equivalent circuit model for patch and ground plane of corner arc monopole antenna using EM software package in the ADS platform and made a good agreement with the proposed antenna. Finally in the third segment RF PIN diode is embedded in a rectangular slot of the patch which achieves desired frequency shifting in the required band of operation.
