Description
Summary:In this paper, a new compact planar antenna is proposed for UWB (Ultra-wideband) operations. The proposed antenna has a low profile structure, consisting of a radiating patch, notched ground plane, and a novel arc-shaped strip connected between the microstrip feed line and the radiating patch. By using the proposed structure, broadband antenna with good impedance matching is obtained. Measured results show that the antenna can achieve a bandwidth of 96.22%. The proposed antenna is optimized in order to satisfy the required band with a good radiation pattern. The fabricated antenna has a compact size of 16 20 1.6 mm3 . These features demonstrate that the proposed antenna is a suitable candidate for UWB applications, due to its simple configuration, compactness, and low fabrication costs.
