Description
Technical field
The utility model relates to communicate, electronic countermeasure and field of navigation technology, specially a kind of novel omnidirectional antenna.
Background technique
Traditional omnidirectional antenna is widely used in mobile communication, electronic countermeasure and navigation every field.The antenna is general
It is all to be made up of vertical symmetry oscillator, monopole and their spin-off, its advantages are exactly the omni-directional ratio in frequency band
Preferably (out-of-roundness is generally within 3dB), but this kind of antenna has several defects, is that gain is not high (usually in passband first
2dBi or so), it is usually butterfly that secondly most critical, which is exactly the antenna pattern of this kind of antenna, that is, is had along the direction of oscillator
Zero point, that is, dead angle, so currently there is an urgent need to a kind of novel omnidirectional antennas to ask to solve the blind area of omnidirectional antenna
Topic.
Summary of the invention
The purpose of this utility model is to provide a kind of novel omnidirectional antennas, are added using completely new back taper antenna oscillator
The structure of metal adjustment bar designs, and to compensate the blind area of aerial radiation, realizes the hemispherical radiation of antenna and the broadband of antenna
Matching properties solve the problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions: a kind of novel omnidirectional antenna, including metal bottom
The upper end of seat, the metab is equipped with medium base, and one end of the medium base is equipped with metal adjustment bar, the medium base
The other end back taper antenna oscillator is installed；Medium is equipped between the medium base and back taper antenna oscillator to match
Plate, the bottom of the dielectric matching plate are provided with feed mouth, which presents connector phase with the coaxial cable that metab bottom is equipped with
Connection.
Preferably, the back taper antenna oscillator is fixed with dielectric matching plate by conducting resinl and rivet interlacement.
Preferably, one end of the metal adjustment bar is fixed with back taper antenna oscillator by rivet interlacement.
Preferably, the metal adjustment bar is a kind of component of L-type structure.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model omnidirectional antenna realizes the radiation of the semi-spherical shape of antenna by the metal adjustment bar of L-type structure, so that
The available effective inhibition in the blind area of aerial radiation；And the width of antenna is realized via back taper antenna oscillator and dielectric matching plate
Band matching, to ensure that the broadband character of radiation.
Detailed description of the invention
Fig. 1 is the overall structure figure of the utility model.
In figure: 1, metab；2, medium base；3, metal adjustment bar；4, back taper antenna oscillator；5, medium matches
Plate；51, mouth is fed；6, coaxial cable presents connector.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, a kind of novel omnidirectional antenna, including metab 1, the upper end of metab 1 are equipped with medium base
2, one end of the medium base 2 is equipped with the metal adjustment bar 3 of L-type structure, and the other end of the medium base 2 is equipped with back taper
Antenna oscillator 4, since one end and the back taper antenna oscillator 4 of metal adjustment bar 3 are fixed by rivet interlacement, to be formed good
Electric conductivity；Dielectric matching plate 5, and back taper antenna oscillator 4 and Jie are equipped between medium base 2 and back taper antenna oscillator 4
Matter matching disc 5 is fixed by conducting resinl and rivet interlacement, reaches satisfactory electrical conductivity, and the bottom of dielectric matching plate 5 is provided with feed
Mouth 51, which is connected with the coaxial cable feedback connector 6 that 1 bottom of metab is equipped with, to feed.
The utility model omnidirectional antenna is realized the radiation of the semi-spherical shape of antenna by the metal adjustment bar 3 of L-type structure, made
Obtain the available effective inhibition in blind area of aerial radiation；And antenna is realized via back taper antenna oscillator 4 and dielectric matching plate 5
Broadband Matching, to ensure that the broadband character of radiation.
In summary: the utility model omnidirectional antenna adds the knot of metal adjustment bar 3 using completely new back taper antenna oscillator 4
Structure design, to compensate the blind area of aerial radiation, realizes the hemispherical radiation of antenna and the Broadband Matching characteristic of antenna, thus has
Effect solves the problems of the prior art.
