Abstract
A unipole antenna arrangement for window pane of a motor vehicle mounted in a metal frame and including a heating field assembled of a plurality of substantially horizontally directed heating conductors, is composed of two superposed sets of substantially vertically directed antenna conductors. One of the sets extends in a first region in the heating field and the corresponding antenna conductors cross at least two horizontally directed heating wires. The antenna conductors in the other set extend in a region which adjoins the marginal heating conductor and terminates by common connection conductor leading to a connection point. The crossing points of the heating conductors and the antenna conductors are interconnected by a galvanic or a capacitive coupling. The connection point of the ends of the antenna conductors in the second set is connected by connection conductor with an antenna coupling point which is located near to the metal frame of the window pane.
