Abstract In this paper, a clover‐shaped microstrip patch antenna for application under an Ultra‐Wide Band (3.1–10.6 GHz) is designed and fabricated. To obtain sufficient bandwidth when the Return Loss is < −10 dB, a partial ground plane and coaxial probe source is used. The measured bandwidth of the fabricated antenna is 8.25 GHz when VSWR <2. Referenced to the center frequency, the gain is 3.20–4.00 dBi. The experimental 3‐dB beam width (HPBW) in the azimuth and elevation are 55.35° and 62.27°, respectively. © 2006 Wiley Periodicals, Inc.
