Abstract

592,490. Directive antenna. STANDARD TELEPHONES & CABLES, Ltd. Nov. 26, 1943, No. 19829. Convention date, Oct. 30, 1941. [Classes 39 (i) and 40 (v)] A directive antenna system comprises a radiating element and an envelope 5 of non- conductive material disposed in intercepting relation with respect to energy radiated by said element containing an ionisable gas, electrodes 6, 7, 8, 9, and 10 being provided which can be successively energized to set up a rotating space charge in the envelope. This will superimpose a rotating characteristic on the pattern radiated by the radiating element. The electrodes may be energized by a two-phase alternator connected to them through a network of rectifiers 14, 15, 16, and 17. In a modification the central electrode 10 can be avoided by the use of an 8-phase alternator supplying an electrode system consisting of electrode pairs AA<1>, BB<1>, &c. Each pair of electrodes may comprise interlocked combs or strips.
