Claim:
A connectors-integrated directional coupler comprising: a cylindrical housing having an input connector integrally extended from one end of the housing and an output connector integrally extended from the other end of the housing; a main line having a main bar and sub bars integrally extending from both ends of the main bar so that the main line connects the input connector to the output connector for delivering a signal; a coupling plate mounted on an outer circumferential surface of the housing; an elongated through hole extending from the input connector to the output connector through the housing for accommodating the main line therein; a coupling line formed on the coupling plate for inducing the signal from the main line thereto; and a planar mounting surface of a predetermined width and length notched in the outer circumferential surface of the housing for mounting the coupling plate thereon and having at least two coupling plates thereon and wherein the housing, the input connector, and the output connector are arranged coaxially.
