Abstract
The present invention provides an internal antenna for mobile terminals that provides performance comparable with externally mounted antennas. The antenna is of a looped dipole configuration wherein the resonating elements of the antenna are integrated within or located on an inside or outside surface of the terminal's housing. The looped-shaped resonating elements may be placed around other components of the phone without significantly infringing on precious, physical space. For example, the loop elements may be placed around the keypad, around the display, around any portion or outline of the housing, and in a flip portion hingeably engaging a main section of the housing. Preferably, the antenna is a two-sided, half-wave antenna having two rectangular-shaped loop dipole elements.
