A compact, CPW‐feed slot antenna for ultrawideband applications is proposed. The antenna uses an elliptical patch as radiating element and an asymmetric slotted ground plane to provide a measured usable bandwidth of 120% (2.81–11.2 GHz). The asymmetric slot in the ground plane creates an extra inductive reactance which neutralizes the capacitive effect of the open ended elliptical patch and results...
