Embodiment Construction

[0020] This specific embodiment discloses a dual-frequency ultra-wideband omnidirectional antenna, such as figure 1 As shown, it includes a biconical antenna unit and a sleeve antenna unit arranged in order from bottom to top.

[0021] The biconical antenna unit includes two cylinder-cone combinations arranged sequentially from bottom to top, which are a first cylinder-cone combination and a second cylinder-cone combination respectively. like figure 1 As shown, the first cylinder-cone combination includes an integrated first cylinder 11 and a first cone 12 , the first cylinder 11 and the first cone 12 are both hollow, and the first cylinder 11 is located below the first cone 12 . The second cylinder-cone combination includes an integrated second cylinder 13 and a second cone 14 , the second cylinder 13 and the second cone 14 are both hollow, and the second cylinder 13 is located above the second cone 14 . It can be seen that the two cylinder-cone combinations are in an inver...

Abstract

The invention discloses a double-frequency ultra-broadband omni-directional antenna. The double-frequency ultra-broadband omni-directional antenna comprises a biconical antenna unit and a sleeve antenna unit which are sequentially arranged from bottom to top; the biconical antenna unit comprises two cylinder-cone combinations which are sequentially arranged from bottom to top, each cylinder-cone combination comprises a cylinder and a cone which are integrated, and the cylinders and the cones are both hollow; the vertexes of the cones in the two cylinder-cone combinations are arranged oppositely and separately, the lower cylinder-cone combination is arranged on a bottom plate, and the upper cylinder-cone combination is fixed to an antenna housing through an isolated first fixing mechanism;the sleeve antenna unit comprises a hollow sleeve, an oscillator is arranged a center shaft of the sleeve, the vibrator and the sleeve are not electrically connected, and the sleeve antenna unit is fixed to the antenna housing through an isolated second fixing mechanism or mounted on the biconical antenna unit through an isolated supporting mechanism; and the antenna further comprises a feed structure for feeding the biconical antenna unit and the sleeve antenna unit. The ultra broadband and good omni-directivity can be achieved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a dual-frequency ultra-wideband omnidirectional antenna. Background technique [0002] With the development of wireless communication technology, spectrum resources are constantly being developed and utilized, which puts forward higher requirements for antennas in terms of multi-function and multi-frequency bands. frequency ultra-wideband omnidirectional antenna. However, the bandwidth of the omnidirectional antennas in the prior art often fails to meet the requirements, and the ultra-wideband antennas often have insufficient omnidirectionality. Therefore, it is necessary to design a dual-band antenna with both ultra-wide bandwidth and good omnidirectionality. SUMMARY OF THE INVENTION [0003] Purpose of the invention: The purpose of the present invention is to provide a dual-frequency ultra-wideband omnidirectional antenna, which has both ultra-wide bandwidth and good omnidirectional...
