A Novel Compact Shorted UWB Antenna

A novel monopole-type antenna, which covers the bandwidth 3.1–10.6 GHz is presented. The shorted and folded planar monopole antenna is constructed by folding a thin copper sheet in such a way that one edge of the radiating element is connected to the ground plane. Simulated and measured results show suitable characteristics for communications systems using ultrawide-band (UWB) technology. Moreover, its reduced dimensions make this antenna a valuable candidate for vehicular, in-door and mobile applications.
