This paper presents a compact shorted patch antenna. The antenna is based on an F-shaped printed conductor coaxially fed with an electromagnetically coupled shorted inverted F-shaped antenna interleaved with each other. The overall antenna is then coupled with a rectangular ring. The antenna has dual characteristic features and its resonance frequency is at 1.85 GHz and 2.42 GHz. The measured return loss bandwidth and its far field radiation patterns are presented. The gain of the antenna is 1.6 dBi.
