1,149,088. Strip line couplers. SIEMENS A.G. 29 Sept., 1966 [30 Sept., 1965], No. 43482/66. Heading H1W. A microwave line comprises a strip conductor 5 provided (e.g. by printing) on one side of a dielectric plate 1, the second conductor of the system being formed by a conductive housing 3 within which lies the dielectric plate 1. The vertical sides of the housing are sufficiently high to prevent radiation of energy whereby a cover plate is rendered unnecessary. The housing may have two screened chambers which intercommunicate over a distance sufficient to provide direction coupling between the lines in each chamber. In order to compensate excess inductive coupling, each strip conductor is provided at either end of the coupling interval with portions which project towards the other strip conductor. Input couplings are provided by coaxial sockets on the housing. A dissipative termination may be formed by arranging wedgeshaped resistive members on either side of a terminal portion of the strip conductor. The terminal portion is tapered to a point. Two microwave lines according to the invention may be joined by abutting the respective housings 31, 32 and inserting a metallic clip 34 between the opposed ends of the lines 35. The clip is roughly in the form of a T with resilient horizontal arms 38 which engage and connect together the strip conductors 35. The vertical limb of the T ends in a pair of spring fingers 37 which enter a recess cut in the housings 31, 32 and engage projecting end portions of the dielectric plates 36. |
