A wideband low‐profile monopolar patch antenna is presented in this article. The proposed antenna consists of a circular‐ring patch shorted to the ground plane by four shorting posts and a coupling patch connected with a feeding probe for bandwidth improvement. This designed antenna can provide a wide operating band (68.5% for VSWR < 2) while keeping a low profile (about 7% of the free‐space wavelength at the lowest operating frequency) and it also offers stable monopole‐like radiation patterns over the operating band. An antenna prototype is fabricated for testing, and the measured results agree well with the simulated ones. © 2010 Wiley Periodicals, Inc.
