The proposed antenna comprises a U-shape like structure with rectangular slot in ground. The partial ground structure with the patch structure is simulated on HFSS 13.0 and then the antenna is fabricated with the inexpensive substrate FR4 and an overall dimension 3 of 25 x 25 x 1.6 mm . The slot structure is used to improve the bandwidth of antenna. The result shows that the proposed antenna achieves good impedance matching. It has a constant gain and stable radiation pattern over the operating band 3.05-6.55 GHz and 9.2-11.6 GHz that covers the most band of UWB. A gain of 3.44 dBi with nearly stable radiation pattern makes the proposed antenna suitable for many different frequency band applications. May - July 2015 Copyright © 2015 i-manager publications.
