Abstract

756,048. Phase shifting and attenuation networks. STANDARD TELEPHONES & CABLES, Ltd. June 19, 1953 [June 25, 1952], No. 17037/53. Class 40 (8). [Also in Group XL (c)] A phase shifter for use in an antenna system (see Group XL (c)) comprises a coaxial line 11 having a gap 15 in its inner conductor 14, and a coaxial inductive stub 18 coupled to the line. An endless carrier such as a disc 16 of low loss material, e.g. fibreglass, and having a metallic rim 17, is moved through the gap 15. In a modification (Fig. 10, not shown), where a large phase shift is required over a large bandwidth, three gaps may be provided in the conductor 14 each having an associated revolving disc and inductive stub. The phase shift may be made a sinusoidal function of time by forming the rim 17 of teeth 23, Fig. 4, shaped so that the width of metal bridging the gap varies sinusoidally. The teeth may be alternately of metal and an insulating material, to alternately attenuate and pass energy, allowing the apparatus to be used as a high-speed capacitive switch. If a gradual phase shift is desired from zero to some upper limit with an almost instantaneous return to zero, the teeth of the rim may be of a triangular shape, Fig. 8. If a phase shift is desired which will vary between two predetermined angles, the teeth may be alternately wide and thin (Fig. 9, not shown).
