Abstract: An on-glass or glass-mount antenna for a motor vehicle has a mounting base incorporating a capacitor plate (4) arranged to be secured to the surface of a window or screen of the vehicle. The radiating element (3) of the antenna is located in substantially the same plane as the capacitor plate (4) and, when enclosed by a protective dielectric cover (9) which conforms closely to the glass surface, provides an aerodynamic and vandal resistant antenna.

Abstract: An electrical connector (1) is to be attached to a circuit board (34) to establish a connection between the board (34) and a coaxial cable. The connector (1) has an outer connector portion (38) formed in a housing (36), and a central conductor element (8) having two limbs (18, 22) joined by an elbow. An insulator assembly comprising a pair of insulating members (2, 4) encloses the central conductor element (8) in the region of the elbow. One limb (18) of the central conductor (8) is located by the assembly in coaxial relationship with the outer connector portion (38) of the housing (36) for engagement with an inner conductor of the cable. The other limb (22) is presented for attachment to the circuit board (34).

Abstract: A coupling unit forming a termination circuit having capacitance and inductance distributed in such a manner as to match and balance a screen mounted antenna comprises a circuit board substrate (1) provided on both sides with patterns of conductive cladding that are configured to provide a capacitor plate (2) for capacitative coupling to a base mounting of the antenna and further elements (3,9,10,12,14,17) that provide the required inductive and capacitative characteristics to enable the termination circuit to match and balance the antenna.
