Abstract

A communications device having an antenna and a housing having a front section and a rear section, one of the front section and the rear section being conductive. A circuit board is mounted within the housing and includes a point of lowest potential and a perimeter of length P. An electrical connection between the conductive one section and the circuit board point of lowest potential has a length less than one-half P.
