摘要：

Many disc antennas have been proposed for ultra-wideband (UWB) applications, but they suffer from the disadvantages of requiring a large ground plane and a complicated feed structure [1-6]. This paper reports on a new and novel co-planar waveguide (CPW) fed disc antenna [7]. Measured data show that the antenna provides more than a 3:1 bandwidth covering the frequency range of 2.4 similar to 10.9 GHz for the tested prototype. Radiation patterns are dipole-like onmi-directional patterns with half power beam width (HPBW) values of 60degrees similar to 70degrees. Maximum gain is about 2 similar to 4 dBi over the bandwidth. The antenna has a good impulse response with less than I nanosecond pulse width and linear phase over a broad bandwidth. The CPW-fed disc antenna is a promising antenna element for UWB applications.
