This paper presents a small printed ultra wideband (UWB) antenna with a coupled slot. This proposed antenna uses coupled L and U slots to broaden the bandwidth. A truncated ground plane is designed to control the antenna's impedance matching. Both slots were designed by investigating the behaviour of the current distribution of the patch antenna. It is shown that by proper design of the slot width and length of those coupled slots, without degrading their performance, a broad bandwidth can be obtained. The antenna's dimension is 30 mm × 30 mm and fed by microstrip line. Both simulated and measured results have shown a good return loss with respect to -10 dB and nearly omni-directional pattern over 2.5 GHz to 10.1 GHz. Thus, this proposed antenna is as potential candidate in UWB application.
