A novel small size coplanar waveguide (CPW)-fed monopole antenna with wide bandwidth and small group delay variation is proposed for ultra-wideband (UWB) applications. It consists of a triangular patch with a pair of wide stabs on the lower sides thereof and linearly tapered coplanar ground planes. The measured return loss of the fabricated antenna is better than -10 dB from 2.9 to 13.2 GHz. The radiation pattern is nearly omni-directional and the variation of the measured group delay between two proposed antennas is less than 0.94 ns over the entire UWB band.
