A small broadband monopole antenna with a vertical ground plane and an electromagnetically coupled feed is presented in this paper. The antenna was formed by positioning a probe with a folded stripline under a shorted square disk. A resonance of the shorted square disk was coupled to a resonance of the probe with a folded stripline, so that the antenna had a wide bandwidth of about 37% at the center frequency of 2.313 GHz based on a VSWR ≤ 2. The antenna had dimensions of 11 mm × 11 mm × 11 mm and rectangular slits were inserted into the vertical ground plane to improve distortion of the radiation pattern. © 2007 Wiley Periodicals, Inc.
