GLIDE-PATH LOCALIZER ANTENNA Russian patent published in 1998 - IPC

FIELD: radio engineering; small- size double-range antennas. SUBSTANCE: arms of folded exciting dipole are bent through 90 deg. towards receiving end. Passive dipole is shortened to 0.1224λ_max and placed in reactive region of exciting dipole at distance of 0.0018λ_max from the latter to ensure capacitive coupling between these dipoles. Both dipoles are arranged in same plane. Folded exciting dipole may be made of coaxial cable. EFFECT: reduced size, enlarged functional capabilities. 2 cl, 1 dwg
