Abstract
An array antenna has rectangular conductor sections, located successively side by side in a first plane, mutually separated by slots of constant width. A backing reflector is transverse to the first plane. Feed structures extend through the backing reflector, the feed structures comprising pairs of parallel feed conductors, each pair comprising conductors coupled to the rectangular conductor sections on opposite sides of a respective one of the slots.
Claims22
An antenna comprising:
- an array of rectangular conductor sections, located successively side by side extending in a first plane, mutually separated by slots of constant width;
- and
- feed structures, each feed structure comprising a pair of parallel feed conductors, a first one of the pair of parallel feed conductors and a second one of the pair of parallel feed conductors ending in galvanic contact with the rectangular conductor sections at the corners of the rectangular conductor sections on opposite sides of a respective one of the slots, wherein at least one of the feed structures comprises:
- a conductor loop associated with the pair of parallel feed conductors, the conductor loop comprising a conductor that runs from the first one of the parallel feed conductors in the pair to the second one of the parallel feed conductors in the pair along a perimeter of a loop area that is not intersected by other conductors;
- and
- a further feed conductor coupled to an input and/or output of the antenna, and electromagnetically coupled to the conductor loop.
