| 摘要 |
The invention relates to a flat antenna system (10) comprising at least one sub-network of radiating elements (a1-a4) arranged on the surface of a substrate superimposed on a ground plane (5), wherein each sub-network consists of a plurality or radiating elements (3) supplied by the sub-network (b1-b4) power supply line to which they are connected, a slit (F1-F4) is embodied in the ground plane (5) in front of each sub-network (b1-b4) power supply line, the system also comprises a power transmission line (G) which is arranged with respect to the ground plane in such a way that an electromagnetic coupling is formed between said power transmission line and each sub-network power supply line by means of the slit. Said invention is characterised in that the power transmission line is positioned in such a way that it extends at an angle to the sub-network power supply lines.
