Abstract	This paper presents various slotted antenna. The proposed antenna is designed in order to meet Ultra Wideband (UWB) requirements and applications. This antenna has small in size enabling it to be fixed into Wireless Personal Area Network (WPAN) devices. There are three types of proposed slotted antennas; T slotted for patch and feeding strip, couple a ring and L slots, and dual asymmetry L slots. From the simulation results, matching bandwidth is due to the shape of the antenna close to the feeding point, where currents are the strongest. It is shown that to better control an antenna behavior, it is necessary to observe the current distributions which give most contribution on matching performance. The T slot on the feeding strip produces more vertical current thus improve the matching impedance performance at higher frequencies, the ring slot with the open angle of 90o and radius (r1) of 3 mm has shown an improvement to the return loss at the lower resonance of 5 GHz and the upper resonance of 10 GHz, the dual asymmetry L slot on rectangular patch has shown multiple resonances. Their simulated return loss and radiation pattern meet the UWB requirements. The slot types are as novelty for this work.
