Abstract
A carrier system for a high-frequency antenna having at least two electrodes situated at a predefined distance from one another and implemented as essentially flat, a dielectric being situated between the at least two electrodes, is distinguished in that the at least two electrodes are situated on a frame part which is as difficult to deform as possible. The frame part preferably has recesses or openings in such a way that air having εr=1 is essentially situated between the at least two electrodes as the dielectric.
Claims16
A carrier system for a high-frequency antenna, comprising:
- at least two electrodes situated at a predefined distance from one another and being implemented as substantially flat;
- a dielectric situated between the at least two electrodes;
- and
- a plastic frame part that is difficult to deform, wherein the at least two electrodes are situated on the plastic frame part;
- wherein the frame part includes one of recesses and openings so that air having εr=1 is essentially situated between the at least two electrodes as the dielectric, wherein a subset of the electrodes situated on one side of the frame part is pre-mounted in the form of an electrically conductive film and the remaining electrodes are situated on a circuit board which has further assemblies for operation of the high-frequency antenna.
