Discone antenna

Abstract

The invention discloses a discone antenna, comprising an upper disc, a center body and support bar parts. The center of the upper disc is provided with a hole which is used for installing the upper end face of the center body, and the tight cooperation between the hole and the upper end face of the center body is realized through an insulation pad. The lower end face of the center body is providedwith a hole for inserting the support bar, and the interference fit is adopted between the hole and the lower end face of the center body. The discone antenna comprises a short oscillator and a longoscillator. The outer surface of the upper disc is evenly provided with a slot for inserting the short oscillator. The periphery of the center body is evenly provided with a slot for inserting the long oscillator. The quantity of the short oscillators is preferably 12, and the quantity of the long oscillators is preferably 12. The discone antenna is in the shape of a conical surface, and is in a unsymmetrical structure. The center of the upper disc is connected to an internal conductor of a coaxial cable, and the conical surface is connected to an outer conductor of the coaxial cable. The longand short oscillators adopt metal rods. The invention is advantageous in that the discone antenna is a vertically polarized and horizontally omnidirectional broadband antenna; the structure is simple, and signal receiving and emitting capability is strong.
