Summary:
small planar UWB (Ultra Wide Band) antenna implemented on a FR-4 substrate is proposed in this paper. Two kinds of ground pattern, 1-stage trapezoid and 2-stage trapezoid, are studied to improve impedance matching. The antenna total size is 40 × 30 mm2 , and the radius of radiating element is 6.2 mm. Both the radiation element and the whole antenna are much smaller than the antenna using a uniform feed line and a conventional square ground.
