Abstract
In an antenna array, in particular for diversity operation, a cohesive radiofrequency-conductive area (1) is provided, to which switchable impedances (7) are coupled in highly resistive fashion. In order to output the antenna signals, at least one tap point (6b) is provided in particular at a highly resistive point at the outer edge of the conductive area (1).
Claims19
An antenna system, for diversity operation in a motor vehicle in particular, comprising the following features:
- at least one cohesive high-frequency-conductive surface (1), which is insulated with respect to a surrounding grounding surface (4), e.g., the vehicle body,
- at least one switchable terminating impedance (7) which is coupled to the at least one conductive surface (1) with a high resistance,
- at least one tap point (6b) for antenna signals on the conductive surface (1), in particular at a high-resistance point in its outer border.
The antenna system as recited in claim 78, wherein the additional conductors (13a, 13b) provided perpendicular to the conductors (1a) run at least partially from the upper edge to the lower edge of the heating field and are at least partially electrically connected or interrupted on the intersection points with the conductors (1a) of the heating field in such a way that a capacitive coupling comes about.
