Reconfigurable slot antenna for cognitive radio applications

A compact UWB monopole patch antenna with reconfigurable ... The UWB antenna is designed on an FR4 substrate with a thickness of 1.6 mm. The relative permittivity of the substrate is Ɛ r = 4.4 and loss tangent is 0.02. The basic configuration of the antenna consists of an elliptical radiating patch with a slot loaded partial rectangular ground plane.
