Abstract
An antenna assembly () includes a ground plane formed on a chassis () of the radio and the functional knob forming an antenna element (). The antenna assembly further includes a slot or notch element () in the ground plane substantially adjacent to the functional knob and having a length less than ¼ wavelength, and a coaxial cable () feeding the antenna element. A shield of the coaxial cable can be directly connected to the ground plane and a center conductor of the coaxial cable can be directly coupled to the functional knob to provide a galvanic connection for narrowband performance or the center conductor can be electromagnetically coupled to the functional knob for wideband performance or both. The antenna assembly can create a zero volume notch type ground excitation.
