The present invention is directed to a dual band, omni-directional antenna having a symmetrical radiating structure defined by a pair of conductive portions interconnected by a tuning bridge formed on a printed circuit board. An outer housing holds the circuit board in place. An adhesive layer is used to secure the antenna to a dielectric, such as the rear window of an automobile. The antenna housing incudes an outer surface includes a plurality of surface interruptions in the form of ridges and valleys that render the housing flexible so that it may conform to the shape of different mounting surfaces. The tuning bridge of the antenna permits tuning of the resonant frequency bands for the radiating structure to define two separate and distinct, selectable frequency bands.

Dual band, glass mount antenna and flexible housing therefor

A multiple use, multi-band antenna for mobile wireless communication and global positioning has includes a elongated cellular radiating element and a GPS radiating element supported atop the cellular radiating element. The cellular radiating element has a continuous body portion of varying diameter that forms a flared upper portion which supports a global positioning system amplifier mounted thereon. The GPS amplifier unit takes the form of a GPS patch radiator disposed atop a low noise amplifier. The cellular and GPS radiating elements are fed by respective first and second feedlines. The stacking of the GPS amplifier unit on the cellular radiating element provides a top loading effect for the cellular radiating element that enables it to resonate across all pertinent cellular frequencies.
