摘要: A method and apparatus for producing an RF part of an antenna system is disclosed, as well as thereby producible RF parts. The RF part has at least one surface provided with a plurality of protruding elements. In particular, the RF part may be a gap waveguide. The protruding elements are monolithically formed and fixed on a conducting layer, and all protruding elements are connected electrically to each other at their bases via the conductive layer. The RF part is produced by providing a die having a plurality of recessions forming the negative of the protruding elements of the RF part. The die may be a multilayer die, having several layers, at least some having through-holes to form the recessions. A formable piece of material is arranged on the die, and pressure is applied, thereby compressing the formable piece of material to conform with the recessions of the die.

摘要: A microwave device, such as a waveguide, transmission line, waveguide circuit, transmission line circuit or radio frequency part of an antenna system, is disclosed. The microwave device comprises two conducting layers arranged with a gap there between, and a set of periodically or quasi-periodically arranged protruding elements fixedly connected to at least one of said conducting layers, thereby forming a texture to stop wave propagation in a frequency band of operation in other directions than along intended waveguiding paths, thus forming a so-called gap waveguide. All protruding elements are connected electrically to each other at their bases at least via the conductive layer on which they are fixedly connected, and some or all of the protruding elements are in conductive or non-conductive contact also with the other conducting layer. A corresponding manufacturing method is also disclosed.
