Abstract

A novel small size microstrip‐fed monopole antenna with wide bandwidth and small group delay variation is proposed for ultrawideband (UWB) applications. It consists of a triangular patch with a pair of wide stubs on the lower sides thereof and linearly tapered partial ground plane on the backside. The measured return loss of the fabricated antenna is better than −9 dB from 2.9 to 12 GHz. The radiation pattern is nearly omnidirectional, and the variation of the measured group delay between two proposed antennas is less than 1.6 ns over the entire UWB band. A good agreement is observed between measured and simulated results. © 2008 Wiley Periodicals, Inc.
