Abstract
A novel single-port wideband discone antenna is proposed, which has variable directivity realised by changing fed cone elements. In the results of the measurements, it is confirmed that the directivity of the antenna can be changed while fractional bandwidth is larger than 0.76. The antenna will improve SINR and reduce transmission power in UWB communication systems adaptively.
