An antenna structure for the transmission and processing of electromagnetic microwave signals is manufactured by making holes in a number of electrically-conductive plates by a mechanical or chemical process in order to create cut-outs in the form of through holes with electrically-conductive edge surfaces. For each plate, the holes have a defined position and length from one side of each plate to its other side. The plates with the holes are stacked in a defined relative position, and the sides of the plates are fixed to each other at least around the edge surfaces formed. In this way, a number of holes are given electrically-conductively limited surfaces in the form of the edge surfaces and also the parts of the side surfaces of the surrounding plate facing the holes.
Method of manufacturing an antenna structure for transmission and processing of electromagnetic microwave signals, said method comprising the steps of
An antenna structure comprising a distribution network for transmission and processing of electromagnetic microwave signals, constructed as a plate structure, in which cut-outs are arranged and which including at least one intermediate electrically-conductive plate with surrounding electrically-conductive plates situated on each side of each intermediate plate, with each side of the surrounding plates in contact with one side or the other side of each intermediate plate, wherein the cut-outs comprise through holes forming cavities with electrically-conductive edge surfaces which form first limiting surfaces in each hole, which extend in each plate's principal plane with a defined position and length for each plate and also extend from one side of each plate to its other side and wherein at least two of the surrounding plates with parts of their side surfaces facing the cavities in an intermediate plate, form second limiting surfaces for the cavities in at least one intermediate plate.
