Abstract :
The use of elliptical coupling apertures between two rectangular parallel waveguides for the realization of intrinsic directional couplers is investigated. It is found that both codirectional and contradirectional characteristics can be obtained. The possibilities of using the intrinsic directional property to improve the characteristics of multielement couplers or to construct filter couplers are examined.
