ABSTRACT:
A wideband monopole antenna including an emitter which is embodied in the form of a disc and vertically arranged at a predetermined spacing above an electrically conductive base plane. The disc-shaped emitter includes a modified section initially having a circular or elliptical disc form, with the modified section being limited by a border outline deviating from the circular or elliptical form.
