Abstract
An antenna system includes a board with an antenna configured to radiate power and a housing. The housing surrounds the board and is configured to protect the board from an environment. The housing includes an opening with at least one metallic wall extending towards the board. The at least one metallic wall is configured to redirect the power radiated by the antenna into a predetermined system radiation direction and in a predetermined radiation pattern.
Claims17
An antenna system comprising:
- a board with an antenna configured to radiate power;
- and
- a housing surrounding the board and configured to protect the board from an environment, wherein:
- the housing includes an opening provided at an edge of the housing with at least one metallic wall extending towards the board up to a predetermined spacing from the board,
- the at least one metallic wall is configured to redirect the power radiated by the antenna into a predetermined system radiation direction and in a predetermined radiation pattern,
- the opening is configured to expose the antenna when seen from a plan view, and
- at least one of the housing or the at least one metallic wall is electrically connected to an electrical ground of the board.
A method of manufacturing a housing for surrounding a board of an antenna system, the housing configured to protect the board from an environment, the method comprising:
- providing a location of the board and an antenna of the board;
- providing a manufacturing technology for providing the housing;
- and
- supplying a metallic material to the manufacturing technology, wherein:
- the manufacturing technology includes a structure for forming the housing with an opening provided at an edge of the housing and having at least one metallic wall extending towards the location of the board up to a predetermined spacing from the board,
- the at least one metallic wall is configured to redirect power to be radiated by the antenna into a predetermined system radiation direction in a predetermined radiation pattern,
- the opening is configured to expose the antenna when seen from a plan view, and
- at least one of the housing or the at least one metallic wall is electrically connected to an electrical ground of the board.
