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.

Dual-band glass-mounted antenna

Vehicle mounted antenna

An omni-directional, collinear, vertical base station antenna having an adjustable or variable radiation beam tilt capability. Terminations at the drive or feed points are provided by an adjustable, capacitive coupling structure at the feed points between the conductive elements of a feed structure and a radiator assembly for adjusting the physical position of the feed points and thereby the phase of the feed points relative to the upper and lower portions of the antenna to alter the deflection angle of the radiation produced. A signal feed, having first and second conductive feed elements, is connectable to a signal feed line to couple a signal between the feed line and the radiator assembly. An adjustable support and control mechanism supports said elongated radiator assembly and said signal feed for relative movement therebetween to effect selective adjustment of the feed points of said capacitive coupling structure along the length of said elongated di-pole radiator assembly to thereby effect adjustment of the beam angle of the radiation pattern.
