Embodiment Construction
[0015] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
[0016] As shown in the figure, an ultra-broadband high-gain omnidirectional antenna includes two radiating units 1 , an insulating support tube 2 , a power divider 3 , a feeder cable 4 and an installation base 7 . The insulating support tube 2 is fixed on the installation base 7, and two identical radiating units 1 are connected in series with the insulating support tube at coaxial intervals. The power divider 3 is arranged on the installation base 7 and passes through the The two feeding cables 4 are connected to the two radiation units 1 respectively.
[0017] The radiation unit 1 includes two identical metal conical cages up and down, the metal conical cages include a metal conical cage 5 and a metal conical cage 6 that are coaxial with the insulating support tube, and the metal conical cage of the upper metal conical cage 5 ...

The invention relates to an ultra-wideband high-gain omnidirectional antenna. Two same radiating units are in serial connection to an insulating support tube at equal interval, and a power distributor is arranged on an installation base and respectively in electric connection with the two radiating units through two feeder cables in the insulating support tube. Each radiating unit comprises an upper metal cone cage barrel and a lower metal cone cage barrel, wherein the upper metal cone cage barrel is the same as the lower metal cone cage barrel, the upper metal cone cage barrel and the lower metal cone cage barrel are oppositely arranged, an opening of the upper metal cone cage barrel is arranged upwards, vibrators at the opening position of the upper metal cone cage barrel are bent inwards the upper metal cone cage barrel to form a coaxial small cone cage, all vibrators at the convergence opening position of the small cone cage respectively, vertically and downwards extend to form a small cylinder cage, vibrators at the opening positions of the metal cone cage barrels of the radiating units are bent inwards to form small cone cages, and vibrators at the convergence opening position of the cone cage respectively and vertically extend downwards to form a small cylinder cage. Double barrels and double cones are arranged in the same direction, vertical polarization is achieved, the size of the omnidirectional radiating antenna is reduced to one fourth of the wavelength of a low frequency band, the bandwidth is increased, and the gain is improved.
Description
technical field [0001] The invention relates to the field of antennas, in particular to an ultra-wideband high-gain omnidirectional antenna. Background technique [0002] In the current communication system, in order to make the communication antenna achieve the desired communication effect, some use a dual-polarized logarithmic periodic antenna or a single-polarized directional antenna, and some use a symmetrical biconical antenna. However, the structure size of these antennas is relatively large, and the three-proof performance is poor. If all-round radiation is required, a drive device and servo equipment are also required, the production is complicated, the consistency is poor, the coverage is affected, and the cost is high. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide an ultra-wideband high-gain omnidirectional antenna. [0004] For achieving above object, ...
