    摘要: An antenna and methods for manufacturing the antenna is provided. The antenna (100) includes an electrically non-conductive substrate (102). The antenna further includes an electrically conductive strip (104). The electrically conductive strip (104) is wound around the electrically non-conductive substrate (102) so as to form an overlap (120) between adjacent turns of the electrically conductive strip (104), without creating a galvanic connection at the overlap.

    摘要: An antenna assembly (10) includes a ground plane formed on a chassis (12) of the radio and the functional knob forming an antenna element (11). The antenna assembly further includes a slot or notch element (14) in the ground plane substantially adjacent to the functional knob and having a length less than ¼ wavelength, and a coaxial cable (13) 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.
