Abstract

1,076,233. Aerials. LAN JEN CHU. Jan. 24, 1966 [Jan. 27, 1965], No. 3125/66. Heading H4A. A broad-band omnidirectional planar aerial comprises a closed loop L from which an array 4 of parallel conductors extends in one direction and a similar but shorter array 4<SP>1</SP> extends in the opposite direction. The loop L comprises a central horizontal section 1, sections 3, 3<SP>1</SP> which are inclined, for example, at Œ60 degrees, shorter horizontal sections 5, 5<SP>1</SP>, and vertical end segments. It is centrally fed by a coaxial cable the inner and outer conductors 2, 2<SP>1</SP> of which are connected, respectively, to the upper and lower segments 1<SP>1</SP>, 1<SP>11</SP> of the section 1. The conductors 7, 7<SP>1</SP> of the arrays 4, 4<SP>1</SP> are vertical and their lengths may be in the ratio 9 : 1. A rectangular frame 9 contains the arrays 4, 4<SP>1</SP> and provides the end segments for the loop L, and the whole may be embedded in a stream-lined plastics housing 11, for use on an aircraft. The aerial is stated to be usable over a 5 : 1 frequency range and relative dimensions in terms of the maximum wavelength # max are given as, overall length = 0À2 # max , width = 0À085 # max , mean length of central portion of loop = 0À01# max .
