Abstract
An antenna array assembly comprises a ground plate, an array of radiator elements disposed in a spaced relationship with a first face of the ground plate between first and second substantially parallel conductive walls projecting from the first face of the ground plate, and a first and second conductive plate. Each of the first and second conductive plates is electrically isolated from the ground plate, and each is disposed in an upstanding relationship to the first face of the ground plate in a substantially parallel relationship with the first and second conductive walls. This provides reduced radiation in at least one direction in the hemisphere on the opposite side of the ground plate to the first face.
Claims21
An antenna array assembly, comprising:
- a ground plate;
- an array of radiator elements disposed in a spaced relationship with a first face of the ground plate between first and second substantially parallel conductive walls projecting from the first face of the ground plate;
- and
- a first and second conductive plate, each being electrically isolated from the ground plate, and each being disposed in an upstanding relationship to the first face of the ground plate in a substantially parallel relationship with the first and second conductive walls,
- whereby to provide reduced radiation in at least one direction in the hemisphere on the opposite side of the ground plate to the first face.
A method of providing increased front-to-back isolation in an antenna array assembly having a ground plate and an array of radiator elements disposed in a spaced relationship with a first face of the ground plate, comprising:
- providing first and second substantially parallel conductive walls projecting from the first face, the first being on one side of the array of radiator elements and the second being on the opposite side;
- and
- providing a first and second conductive plate, each being electrically isolated from the ground plate, and each being disposed in an upstanding relationship to the first face of the ground plate in a substantially parallel relationship with the first and second conductive walls.
