✦ Synopsis

A novel UWB (ultra-wideband) printed monopole antenna consisting of a circular monopole patch and a trapeziform ground plane with a tapered CPW (coplanar waveguide) feeder in the middle is introduced. By means of the trapeziform ground plane and the tapered CPW feeder, the impedance bandwidth is broadened greatly. Both the simulated and experimental results are presented, showing good agreement and verifying the validity of the design. The experimental results demonstrate that this antenna achieves an 11.3:1 ratio bandwidth of VSWR Յ 2, covering frequencies from 0.79 to 9.16 GHz, and exhibits an omnidirectional radiation pattern with a simple structure, which is attractive for UWB communication applications.
