ABSTRACT:
A microwave antenna is described, having a substrate (11), at least one resonant metallization structure (1) and at least a first and a second feed point (3, 4, 6, 7) for coupling in HF power to be radiated, said antenna being particularly suitable for surface mounting on a printed circuit board (20). The feed points (3, 4, 6, 7) are so arranged in this case that, for different positions of the antenna (10) on a printed circuit board (20), it is in each case possible to select a feed point in which case the electrical properties of the antenna (10) are at least substantially unchanged.
