Ultrashort wave folding type discone antenna

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.
