METHOD OF MANUFACTURING AN ANTENNA STRUCTURE AND AN ANTENNA STRUCTURE MANUFACTURED ACCORDING TO THE SAID METHOD

摘要

An antenna structure for the transmission and processing of electromagnetic microwave signals is manufactured by making holes in a number of electrically-conductive plates (1-7) by means of a mechanical or chemical process in order to create cutouts in the form of through holes (8-14) with electrically-conductive edge surfaces. For each plate these have a defined position and length in each plate's principal plane and also a 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. By this means a number of holes (9, 11, 13) are given electrically-conductive limit surfaces in the form of the said edge surfaces and also the parts of the side surfaces of the surrounding plates (1, 3, 5, 7) facing the holes.
