Summary:A novel pattern reconfigurable planar ultra wideband 2×2 antenna array is presented. This UWB planar array has a high gain that can be useful in sensing the spectrum for cognitive radio applications. The array can provide basic pattern reconfiguration to enhance the scanning and the communication performance in cognitive radio operation by limiting interference coming from specific directions. The reflection coefficient, radiation patterns, gain and total efficiency simulations of the UWB mode and the reconfiguration modes are presented. The pattern reconfigurablity of the proposed antenna is also investigated by simulating indoor coverage and power received in a realistic environment for different pattern configurations.
