Title:
導波路変換部の接続構造、その作製方法、及びこの接続構造を用いたアンテナ装置
Document Type and Number:
Japanese Patent JP5383796
Kind Code:
B2
Abstract:
A connecting structure of a waveguide converter includes a circuit substrate (2) in which a hollow waveguide (11) that propagates a high frequency signal is formed in a pierced manner; and an antenna substrate (4) that is layered on the circuit substrate (2), and in which a converter (22) that is arranged at a connecting point with the hollow waveguide (11) and a strip line (16) that extends from the converter (22) and that propagates the high frequency signal are provided. A choke circuit (21) to shield a leak of the high frequency signal is arranged around the hollow waveguide (11) on a surface of the circuit substrate (2) opposing to the antenna substrate (4) so as to surround the hollow waveguide (11) keeping a predetermined interval from the hollow waveguide (11), and the circuit substrate (2) and the antenna substrate (4) are fixed to each other by adhesive (20) that is arranged at a position outside the choke circuit (21), between the substrates.
