The characteristics of an ultra-wideband (UWB) planar monopole antenna with multiple simple slots is presented. By placing a pair of symmetrical horizontal slots on the sides of the monopole antenna a tune-able notch characteristic can be obtained. The length, width and height of the slot can be used to tune the centre frequency, bandwidth and re∞ection coe-cient of the notch. Placing two pairs of horizontal slots on the sides of the monopole antenna two tune-able notched characteristics can be obtained. Based on slot length and slot position an approximate formula for the notch centre frequency is given. The results of simulation and measurement are presented and discussed.
