Receiver module for receiving extremely high frequency electromagnetic directional radiation fields

DETAILED DESCRIPTION I claim: 1.
Reception module for the reception of extremely high frequency electromagnetic directional radiation fields, consisting of a group of surface resonators which are excited by means of a coupling network, and coupled among one another, in which the coupling network leads to a central feed point of defined impedance characteristic, characterized in that an array of highly conductive surface elements of defined geometry as well as of defined positioning condition is arranged on a dielectric carrier in such manner that on the two oppositely lying parallel planes of the dielectric carrier there arise congruent element groupings; the dielectric carrier is arranged parallel to a closed highly conductive plane, so that the parallel planes run distance-homogeneously to one another; the surface elements of the two parallel-running element planes have both agreeing contours and also agreeing outside measurements; the surface elements are characterized by two like or unlike symmetry planes and have in each case in one of the two symmetry planes two circular diaphragms or in each of the two symmetry planes in each case two circular diaphragms, the circular diaphragms with reference to planes being in each case at the same distance from the intersection point of the surface diagonals for the case of rectangular surface elements, or from the starting point of the radius vectors for the case of circular surface elements; the symmetry planes in which the diaphragms are arranged are with respect to planes disposed spatially orthogonally to one another; the electromagnetic excitation of the surface elements occurs by means of coaxial waveguide diaphragms, the axes of which run spatially parallel to the surface normal of the dielectric carrier; the coaxially waveguide diaphragms are arranged in such manner that their axis in each case runs along a section plane which forms an angle of 45.
degree.
with respect to the section planes along which the axes of the circular diaphragms run; the coaxial waveguide diaphragms consist of a coaxial waveguide the outside conductor of which forms the galvanic continuation of the closed highly conductive plane and the inside conductor of which issues axially into the circular diaphragm of the plane facing the parallel and highly conductive plane, the plane facing away from the highly conductive plane not being galvanically contacted
