A simple pattern reconfiguration approach of an Ultra Wide Band (UWB) monopole antenna is presented. By inserting a VIVALDI shape in the Coplanar-Waveguide (CPW) ground plane, the pattern reconfiguration is achieved without changing the original size and form of the monopole. Only two switches were used, thus the main beam is controlled depending on the state of these switches. Therefore, in the band of reconfiguration, the antenna radiates in three different directions (two directive states and one omnidirectional state). Switches were inserted in specific locations so that to eliminate currents to distribute and to radiate from that side, hence the main pattern is shifted in the other side. The proposed approach can be applied to different CPW-Fed monopoles, consequently, it may be suitable for domains were dynamic pattern reconfiguration is needed such as tracking, cognitive radio etc. Our approach is applied to two monopoles: printed stepped rectangular monopole and circular disc antenna. Furthermore, realized prototype and measurements are carried out.
