Abstract

624,527. Aerials. WEIGHTON, D., and PYE, Ltd. Dec. 20, 1946, No. 37478. [Class 40 (vii)] A radio antenna array comprises a plurality of radiating elements spaced from and disposed in helical formation around a mast and feeder, and having the radial angle between adjacent elements proportional to their longi - tudinal spacing relative to the wavelength. Horizontal elements 1, 2, 3, &c. which may be centrefed half wavelength dipoles are supported on quarter wavelength struts projecting from mast and feeder 200 at points 101, 102, 103, &c. a quarter wavelength apart. The radial angle between adjacent elements is made 90 degrees, whereby elements 1, 5, &c. are fed in phase, and in antiphase to elements 3 &.c. which are spaced away by a half wavelength. Similar conditions arise in the two sets of even numbered elements which are then in space and phase quadrature to the odd numbered elements. The resulting radiation pattern is substantially circular in the horizontal plane and horizontally directive in the vertical plane. In an alternative arrangement the radiating elements may be vertical.
