Abstract
A planar microwave antenna for receiving radio and television satellite signals, in which the antenna is associated with a main beam direction that is freely adjustable regardless of the position of the main plane of the antenna. The antenna is rotatable about its vertical axis, which is perpendicular to the main plane, and the main beam direction is adjustable in a plane running perpendicular to the main plane by adjusting phase shifting elements acting on the individual signals in the form of essentially U-shaped draw-out lines. The antenna may be a two-shell design, in which each of the two shells have individual antenna elements that are directed in different main mutually perpendicular directions. A decoupling element, which may include a round, hollow-cored conductor, may be mounted so that it is rotatable relative to the main plane of the antenna so that any linear polarization direction can be set.
