Title:
FOUR-WIRE BACK FIRE HELICAL ANTENNA
Document Type and Number:
Japanese Patent JP2719857
Kind Code:
B2
Abstract:
PURPOSE: To reduce man-hour for work by connecting the first terminal part connecting part of a first radiating member to a coaxial central conductor, a second terminal part connecting part to a coaxial outer conductor and the first and second terminal part connecting parts of a second radiating member to the coaxial outer conductor.
CONSTITUTION: Radial conductors 5 and 7, arm 13 and rear connector 49 are integrally formed at a first radiating member 14. Second radiating members 9 and 11, arm 27 and rear connector 50 are integrally formed. In the state of facing the first and second bent radiating members 14 and 16 each other, a through hole is inserted to a coaxial cable 38 and soldered to the soldering part of the coaxial outer conductor, the arm 13 is soldered to the soldering part of a coaxial central conductor 39 and the arm 27 is soldered to the soldering part of a coaxial outer conductor 43. Therefore, the number of parts can be decreased, and connecting parts in the case of assembly can be reduced.
