Abstract (en)
[origin: EP0097932A1] 1. A micro-wave radio relay antenna of mussel-shaped construction, comprising a reflector (1) designed as an eccentric section of a paraboloid of rotation and supplied by a primary radiator system in accordance with the offset principle, and bounded at its sides and its base by metallic walls (3, 4, 5), characterised in that at the level of that part (2) of the primary radiator system which directly irradiates the reflector (1), the length of the lateral boundary walls (3, 4) in the antenna radiation direction is contrived to be approximately such that this part (2) of the primary radiator system - when projected onto the lateral boundary walls - lies approximately in the centre between the antenna aperture and the reflector (1), that the rectilinear, aperture-side edges of the two lateral boundary walls (3, 4) extend such that the surface vector (e) at right angles to the aperture is directed obliquely upwards when the primary radiator system (2) is in the lower position and is directed obliquely downwards when the primary radiator system is in the upper position, that the lateral boundary walls (3, 4) are bent inwards and the bend lines (10, 11) extend approximately vertically, and that when that part of the primary radiator system which directly irradiates the reflector (1) is projected onto the lateral boundary walls (3, 4), the bend lines (10, 11) lie between this part (2) and the aperture.
