Abstract :
A planar tapered-CPW-fed monopole antenna, consisting of a circular patch and a trapeziform ground plane, is introduced. Both circular patch and ground plane are printed on the same side of a thin substrate, therefore the antenna can be easily fabricated with low cost, and achieve an extremely wide impedance bandwidth because of the tapered CPW feeder and trapeziform ground plane. The experimental results demonstrate that the antenna obtains a VSWR≤2 bandwidth of 9.2:1, covering frequency range from 0.97 GHz to 8.98 GHz, which is suitable for applications in UWB communications and radars.
