ABSTRACT:
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.
