Title:
PATCH ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/054216
Kind Code:
A1
Abstract:
The present invention comprises: a double-ridge wave guide having a double-ridge wave guide tube part that has first protrusions disposed opposing each other, through which a first radio wave propagates in a first propagation mode, and in which the cut-off frequency, of a second radio wave, in a second propagation mode is set higher than the frequency of the second radio wave, and having a first signal conductor that inputs, to the double-ridge wave guide tube part, a signal to be converted to the first radio wave; a quad-ridge wave guide having a quad-ridge wave guide tube part that is connected to one end of the double-ridge wave guide tube part at the other end, that has second protrusions disposed opposing each other in manner continuous to the first protrusions and has third protrusions disposed opposing each other between the second protrusions, and through which first and second radio waves propagate, and having a second signal conductor that inputs, to the quad-ridge wave guide tube part, a signal to be converted to the second radio wave by the quad-ridge wave guide tube part; and a patch conductor holder that is disposed to one end of the quad-ridge wave guide tube part. Continuous bodies including the first protrusions and the second protrusions have notches, which cause intervals between end faces of opposing continuous bodies, formed at a boundary portion between the double-ridge wave guide tube part and the quad-ridge wave guide tube part.
