Abstract
AbstractA compact hollowed printed monopole antenna with an extremely wide bandwidth is introduced, which is composed of a hollowed elliptical monopole patch and a trapeziform ground plane, both printed on the same side of a substrate, and is fed by a tapered CPW feeder in the middle of the ground plane. The simulated and experimental results agree well and demonstrate that this antenna achieves a measured impedance bandwidth from 0.44 to 10.6 GHz (24.1:1) for VSWR ≤ 2, and exhibits a nearly omnidirectional radiation pattern, while its area is only about 0.20λl × 0.13 λl, where λl is the wavelength of the lowest operating frequency. © 2007 Wiley Periodicals, Inc.
