Abstract
An antenna assembly for multiple band operation of a wireless communications devices such as cellphones. Embodiments of the present invention provides for operation over 824-960 MHz Cellphone and 1575 MHz GPS bands and 1710-2155 MHz. Coverage over the GPS frequency band is highly desirable for wireless communication devices such as cell phones, in order to provide location information. Radiating conducting elements can be positioned in close proximity to an inverted PIFA-type antenna, requiring very little additional space or volume and allowing nearly the same form factor to be used for the antenna assembly. An illuminated panel may be positioned within an aperture of the ground plane. The panel may be back lit and activated in response to an external signal.
