Abstract
A dual-band antenna assembly configured to be mounted on a dielectric substrate such as an automobile window glass. The dual-band antenna assembly is adapted to transmit and receive signals in two distinct frequency bands, particularly the cellular frequency band, 800-900 MHz and the PCS frequency band 1.8 GHz. The antenna assembly is further configured to couple signals in either frequency band through the dielectric so that signals originating on a first side of the dielectric substrate may be coupled to the antenna-radiating element located on the opposite side of the dielectric substrate and signals received by the antenna on the second side of the dielectric substrate may be coupled through the dielectric to a mobile telephone located on the first side of the substrate. Thus, signals originating from a mobile telephone unit located within a vehicle may be coupled to and transmitted by an antenna element on the outside of a vehicle, and signals received by the antenna maybe coupled to the mobile telephone inside the vehicle.
