ABSTRACT:
A motor vehicle antenna pane with improved diversity and/or multiband applicability in the VHF range for mounting in a metal surround (1) provided with a conductive panel (2) spaced from the metal surround (1) such that an elongated dielectric slot (3) is produced between the two. In the slot (3) are arranged a number of slot antennas incorporating elongated radiating areas (4,5) extending along the length of the slot (3) the geometric forms of which are bounded by an HF-conductive frame incorporating at least one ground edge conductor (1,6, 7) and one signal edge conductor (2, 8, 9) and at least one terminating conductor (10, 11) terminating the slot antennas at their longitudinal ends. Each of the radiating areas (4,5) incorporates a terminal area (12, 13) in which at neighbouring terminal points (14, 15, 16, 17) the ground conductor (19 of an unbalanced connecting lead (18,21) assigned to the respective slot antenna may be connected to the ground edge conductor (1,6,7) and its signal conductor (20) may connected to the signal edge conductor (2, 8, 9) of the respective slot antenna.
