Abstract
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.
