Abstract
A flexible waveguide device, of the bellows type, for guiding a radio frequency signal at a given frequency range. The device includes: a core including outer and inner side walls, the inner walls delimiting a waveguide channel; two fixing flanges connected to or integral with respective ends of the core, and at least one flexible corrugated portion formed on a part of the outer side walls of the core and including a plurality of circumferential ribs adjacent to each other. Each rib is devoid of corrugation along its circumference. Also, a method of manufacturing the flexible waveguide device.
Claims15
Method of manufacturing a flexible waveguide device, of the bellows type, comprising a core through which a channel passes in order to guide a radio frequency signal at a given frequency, the method comprises the following steps:
- making by additive manufacturing a mandrel having an outer shell comprising a corrugated portion having a plurality of adjacent circumferential ribs,
- depositing a metal layer on the outer shell of the mandrel by electroforming to form the core of the device, and
- removing the mandrel from the electroformed metal layer to define the channel,
- wherein the mandrel is manufactured so as to obtain a hollow mandrel.
Flexible waveguide device, of the bellows type, for guiding a radio frequency signal at a given frequency range, the device comprising:
- a core comprising outer and inner side walls, the inner walls delimiting a waveguide channel,
- two fixing flanges connected to or integral with respective ends of the core, and
- at least three flexible corrugated portions formed on respective parts of the outer side walls of the core and comprising a plurality of circumferential ribs adjacent to each other,
- wherein each rib is devoid of corrugation along its circumference.
