A simple circular‐ring planar‐monopole antenna, with a compact size of 26 × 28 mm2, fed by an offset‐microstrip line, is proposed. The antenna is composed of a circular‐ring radiator and a ground plane with a small rectangular slot cut along the upper edge for ultra‐wideband (UWB) operation. Studies of the antenna are carried out using computer simulation. Prototype of the antenna is used for verification...
A printed circular ring antenna for UWB application is proposed in this paper. The antenna structure is composed of a circular ring patch and a partial ground plane. The proposed antenna has a total size of 39 × 40 mm2. The measurement shows that the antenna has an impedance bandwidth (VSWR≤ 2) of 9.54 GHz (2.54 to 12.08 GHz). A nearly stable bidirectional radiation pattern with low cross polarization...
