Abstract

The invention discloses an ultrashort wave folding type discone antenna which comprises a telescopic component, a core rod, a top control disk, a sliding shaft, a flange casing, a main supporting pipe, a vertical-polarization conductor casing, a lower connecting disk, an upper connecting disk, eight horizontal-polarization long oscillators, eight horizontal-polarization short oscillators, eight oblique-polarization antenna vibrators and a signal processing circuit module. Under the mode that the operating frequency range of ultrashort waves is met, the range of operating frequency range of the antenna is expanded furthest to 20-3600MHz, and the signal receiving sensitivity is improved. The structure size of the antenna is reduced furthest, the weight is decreased, the size is reduced, and the force distribution of the whole cylindrical antenna structure is improved.

Description

technical field

[0001] The invention relates to an antenna, in particular to an ultrashort-wave refraction-type disc-cone antenna. Background technique

[0002] At present, all devices that use electromagnetic waves to transmit information require antennas. Therefore, in the fields of broadcasting, communications, meteorology, aerospace, and electronic countermeasures, antennas have become a key component of the system.

[0003] At present, there are various forms and types of antennas, among which the columnar antenna is a structural form widely used in the antenna structure. The electrical performance requirements of the antenna must also meet the mechanical performance requirements of the antenna. For portable equipment, it must also meet the requirements of erection, disassembly and carrying, that is, the antenna is required to be light in weight, small in size, and can be quickly assembled and disassembled.

[0004] Generally, the cylindrical antenna designed by the tr...
