Abstract

761,765. Microwave transmission lines. STANDARD TELEPHONES & CABLES, Ltd. May 1, 1953 [May 8, 1952], No. 12114/53. Class 40 (8). A transmission line of the strip type described in Specifications 704,050, 708,601 and 761,764 is provided with means for adjusting the line wavelength of a short section of line. The transmission line comprises a " line " conductor 1 separated from a " ground conductor 2 by a layer of dielectric 3 a small fraction of a quarter wavelength thick. Overlying a narrowed portion 4 of the conductor 1 are two conductive strips 5, 6 which can be moved towards and away fron each other by means of a two cam-and-pin mechanisms 12, 15 which are geared together by an endless cord 17. The strips 5, 6 are maintained in contact with the line conductor 1 by straps 21, 22. Adjustment of the strips 5, 6 causes variation of the effective width of the line-section and hence of the line wavelength. In a second method of actuating the strips 5, 6 (Figs. 7, 8, not shown) a rack- and-pinion mechanism is used. The pinion engages the dielectric layer by means of a screwthread and penetrates to an adjustable degree into the 'dielectric as the position of the strips 5, 6 is adjusted. It is stated that the degree of penetration effects to some degree the wavelength of the section. In the modification of Fig. 5, the " ground " conductor 29, the " line " conductor 28 and the dielectric layer 30 are of the same width and adjustment of the wavelength of the section is effected by securing additional strips of dielectric 33, 34, 35, 36 to the edges of the layer 30, e.g. by means of pins 31. These strips may have conducting layers on one or both sides. The wavelength may also be changed by changing the dielectric material in a section of the line. To this end a card made up of strips of different dielectric materials may be slid between the " line " and the " ground conductors (Fig. 9, not shown). Where the dielectric comprises a foamed material it is necessary to increase the density of the material towards the ends of the strip in order to prevent mismatch. Interchangeable strips of dielectric 50, Fig. 10, shaped as shown to produce a gradual transition, may be used to effect the desired change of wavelength.
