Antenna apparatuses and methods used in wireless communication devices are disclosed. The antenna includes a first portion configured to be coupled to a communication device. The antenna also includes a second portion configured to be coupled to the first portion. The first portion and second portion are coupled by overlapping the first portion and second portion so as to produce an omnidirectional radiation pattern and a vertical radiation pattern.

Antenna configuration

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

Antenna and method of forming same

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 &#xbc; 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.
