Abstract
The disclosure relates to an antenna arrangement, including an antenna mounted inside a radome. The antenna arrangement further includes a mounting arrangement arranged to mount the antenna arrangement to an antenna platform. The antenna is a tapered slot antenna, the radome has an aerodynamic shape, and the mounting arrangement includes two antenna fastening means and an antenna radio frequency connector arranged to interact with corresponding antenna platform fastening means and an antenna platform radio frequency connector arranged on the antenna platform.
Claims7
An antenna arrangement, comprising an antenna mounted inside a radome, a mounting arrangement attached to the radome arranged to mount the antenna arrangement to an antenna platform, wherein:
- the antenna is a tapered slot antenna,
- the radome has an aerodynamic shape, and
- the mounting arrangement comprises two antenna fastening means and an antenna radio frequency connector arranged to interact with corresponding antenna platform fastening means and an antenna platform radio frequency connector arranged on the antenna platform,
- wherein the antenna arrangement is arranged on an essentially vertical surface of the antenna platform such that the antenna arrangement is arranged to receive and transmit radio frequency signals that are horizontally polarized and propagates perpendicular to a direction the antenna platform is moving.
A method for receiving and transmitting radio-frequency signals with horizontal polarization and propagation perpendicular to a direction in which an antenna platform is moving, wherein the method comprises:
- providing an antenna arrangement by mounting a tapered slot antenna inside an aerodynamically shaped radome,
- further providing the antenna arrangement with a mounting arrangement comprising two antenna fastening means and one antenna radio frequency connector,
- arranging, on a vertical surface of an antenna platform, an antenna platform fastening means and an antenna platform radio frequency connector arranged to interact with the antenna fastening means and an antenna radio frequency connector, and
- attaching the antenna arrangement to the antenna platform and connecting the antenna arrangement to a control system through the antenna radio frequency connector and the antenna platform radio frequency connector,
- wherein the antenna arrangement is arranged on the vertical surface of the antenna platform such that the antenna arrangement is arranged to receive and transmit radio frequency signals that are horizontally polarized and propagates perpendicular to a direction the antenna platform is moving.
