PROBLEM TO BE SOLVED: To provide a waveguide filter suppressing spurious with a simple configuration. SOLUTION: In the waveguide filter 1 where a plurality of waveguide resonators 2 composed of space are connected via an inter-resonator window 3, the inter-resonator window 3 is provided at a position having a lower electric field strength of spurious within the waveguide resonators 2. Thus, the spurious cannot be easily transmitted to the adjacent waveguide resonators 2 via the inter-resonator window 3 and transmission of the spurious is suppressed. COPYRIGHT: (C)2011,JPO&INPIT |
