Abstract
The unitary cellular telephone antenna includes a junction box to which is mounted both the antenna element, preferably a 5/8 wavelength antenna, and two 1/4 wavelength downwardly oriented radials to establish the antenna's ground plane. Electrical elements are included within the junction box to match the impedance of the antenna system to the cellular telephone transceiver and to maximize the radiated signal.
Claims1
A unitary cellular telephone antenna assembly comprising:
- a junction box having a plurality of planar surfaces;
- a fractional wavelength antenna;
- means mounting the antenna on one of the planar surfaces of the junction box so that when the junction box is mounted on a surface, the antenna projects generally vertically upward from the box;
- a plurality of ground plane radial elements;
- means mounting the radial elements on planar surfaces of the junction box such that the radial elements are angled downwardly relative to the horizontal plane perpendicular to the vertical antenna;
- connector means mounted to the junction box for attaching the antenna and radial elements to a cellular telephone transceiver;
- the junction box including a metalized area about an opening;
- a nut being attached to the metalized area about the opening;
- a suction cup;
- and
- a bolt received in the suction cup, the threaded shaft of the bolt being received in the nut to attach the suction cup to the junction box, whereby the antenna assembly may be conveniently attached by the suction cup to a relatively smooth surface.
