A novel and simple frequency and pattern reconfigurable single element ultra-wideband monopole antenna realised in a compact design is presented. The antenna occupies overall dimensions of 34×31×0.88 mm3. The antenna can switch from ultra-wideband operation to narrowband operation with three different radiation pattern configurations. Three p-i-n diodes are used as switches and their package and biasing...
A novel pattern-reconfigurable compact planar ultra-wideband monopole antenna is presented. By the incorporation of four p-i-n diode switches and two parasitic elements, the antenna's radiation patterns can be shaped to concentrate energy in specific directions while minimising the gain in other unwanted directions without significantly affecting the impedance bandwidth of the antenna. A fully functional...
