Title:
WAVEGUIDE CONNECTION STRUCTURE
Document Type and Number:
Japanese Patent JP2013168830
Kind Code:
A
Abstract:
To suppress influences exerted upon a frequency band to be used even if a gap is generated between connection surfaces when waveguides are connected.
A length L1 from openings of waveguides to ends of connection surfaces is adjusted in accordance with a frequency band to be used. Therefore, even if a gap is generated between the connection surfaces when the waveguides are connected to each other while matching the connection surfaces, bands to be affected in propagation characteristics are out of the frequency band to be used, thereby preventing a system performance from being impaired.
