In this paper, a miniaturized elevated-coplanar-waveguide-fed antenna with a slotted ground plane is proposed. This antenna has a compact size of 25 mm × 25 mm × 1.6 mm where the ground plane is reduced by etching a trapezoidal slot along with two extended slits. A −10 dB wide-impedance bandwidth of 126% ranging from 2.8 to 12.4 GHz is achieved for the proposed antenna. The proposed antenna is successfully manufactured and experimentally investigated. The measurement shows a good agreement with the simulation. The measured radiation characteristic shows a stable and nearly omnidirectional pattern over the operating bandwidth region. The effects of various parameters on the antenna performance are analyzed and discussed as well.
