COLLAPSIBLE SPIRAL ANTENNA Russian patent published in 1995 - IPC

Abstract RU 2046471 C1

FIELD: antenna equipment. SUBSTANCE: collapsible spiral antenna has flat metal reflector 6 and row of conductive spirals 2 fixed on reflector 6 by means of dielectric cylinders with metal bases 5 and energized with the aid of coaxial cables 9-13. Energizing device 4 is put on each metal base 5. Dielectric cylinders with conductive spirals 2, flat metal reflector 6 and feeding cables 9-13 are made separable. Description gives relationships for determination of dimensions of dielectric cylinders with spirals 2, flat metal reflector 6 and distances between dielectric cylinders 1. EFFECT: expanded application field. 5 dwg
