Abstract
668,223. Aerials; aerial coupling arrangements. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 21, 1950 [Dec. 23, 1949], No. 33022/49. Classes 40 (v) and 40 (vii). A coupling unit for energizing a metalskinned aircraft wing as an aerial comprises a metal-walled shallow recess d<SP>1</SP>, d2, d<SP>3</SP> in the leading edge a of the wing, the mouth of the recess being closed by an insulating cover e on the underside of which is mounted a copper strip f, the inboard edge of the conductor being connected to the inner conductor of a coaxial feeder g whose outer conductor is bonded to the adjacent wall d<SP>1</SP> and the outboard end being curved at f<SP>1</SP> so as to be capacitatively coupled to the wall d<SP>3</SP> and a protruding portion a<SP>1</SP> of the edge; alternatively a condenser may be connected between the end of the conductor and the edge of the wing. The recess is preferably #/4 long and #/10 deep and the portions e, f, a<SP>1</SP>, d<SP>1</SP> and d<SP>2</SP> may comprise a detachable unit, the wall d<SP>2</SP> being formed by the main spar of the wing. Two of the coupling units may be employed as disclosed in Specification 668,222 to produce a substantially omni-directional polar diagram.
