Abstract (en)
[origin: WO9948167A1] An antenna device for microwave radio communication comprising feed connection means (5) having a hot conductor and a ground conductor for connecting said device to a radio transceiver, magnetic fastening means (25) having first and second opposed sides for fastening at its first side the device to a steel body to be acting as a ground plane means, conductive ground coupling means connected to the ground conductor, radiator means (16-20) including a helical filter means (19) and connected to the hot conductor. The ground coupling means including said magnetic fastening means (25) and a metal member (23) adjacent to the second side of the magnetic fastening means (25), wherein the metal member (23) and the magnetic fastening means (25) being arranged so as to provide radio frequency contact to the steel body to be acting as a ground plane.
