DIPLEXER AND MULTIPLEXER
First Claim
1. A diplexer comprising:
- a first directional coupler that is comprised of a first waveguide and a second waveguide;
a second directional coupler that is comprised of a third waveguide and a fourth waveguide;
a first filter that resides between the first waveguide and the third waveguide; and
a second filter that resides between the second waveguide and the fourth waveguide,the first filter and the second filter each including a plurality of resonators that are electromagnetically coupled,the plurality of resonators each having a broad wall that is in a shape of a circle or a regular polygon with six or more vertices,two resonators, which are coupled together, of the plurality of resonators being arranged such that D<
R1+R2 is satisfied, where R1 and R2 represent radii of circumcircles of the broad walls of the two resonators and D represents a center-to-center distance between the two resonators.

Abstract
A diplexer (100) includes: first and second directional couplers (106A, 106B); and first and second filters (101A, 101B). The filters (101A, 101B) each include a plurality of resonators (110A to 150A, 110B to 150B) that are electromagnetically coupled. The resonators (110A to 150A, 110B to 150B) each have a broad wall that is in a shape of a circle or a regular polygon with six or more vertices, and two resonators, which are coupled together, of the resonators (110A to 150A, 110B to 150B) are arranged such that D<R1+R2 is satisfied, where R1 and R2 represent radii of circumcircles of the broad walls of the two resonators and D represents a center-to-center distance between the two resonators.
