Patent ID: 10930994

Abstract:
The present disclosure relates to a waveguide transition arrangement (1) comprising a first ground plane (6) with a first aperture (7), a feed probe (4) that crosses the first aperture (7), a second ground plane (8) with a second aperture (9), and a waveguide resonator part (10) that has an opening (11) that faces the second aperture (9). The first ground plane (6) faces the second ground plane (8) and is positioned between the feed probe (4) and the second ground plane (8), and the second ground plane (8) faces the waveguide resonator part (10). A wall structure (12) is at least partly arranged between the first ground plane (6) and the second ground plane (8) such that a first cavity (13) is formed in an enclosed volume between them. The first aperture (7) and the second aperture (9) are electromagnetically connected to the first cavity (13), and where the second aperture (9) to a second cavity (14) in the waveguide resonator part (10) which is electromagnetically connected to a waveguide section (15) via a third aperture (16).
