Description
Technical field
The utility model belongs to wireless communication devices technical field, especially relevant with a kind of cylindrical shape multiple-input and multiple-output Yagi antenna.
Background technology
Yagi antenna, the end-fire antenna arranged in parallel by an active dipole (generally using folded dipole), a passive reflector and several passive directors.Yagi antenna has good directivity, has high gain compared with dipole antenna.Direction finding, telecommunication effect is come good especially with it.Publication number is that CN 203260728U discloses a kind of antenna, comprise: reflector and be located at least one antenna unit array of reflecting surface side of described reflector, described antenna unit array comprise multiple there is the first working frequency range the first antenna element and at least one there is the second antenna element of the second working frequency range, described multiple first antenna element surrounds one week, and described second antenna element is positioned among described one week the first antenna element.But the structure of this antenna is cylindrical shape, the mimo antenna array of three Yagi antenna unit compositions, Yagi antenna active dipole part and director dipole are all printed on pcb board, this antenna is printed in copper-clad plate, if use low-cost copper-clad plate, then dielectric loss is comparatively large, and antenna efficiency is lower.If with the copper-clad plate that dielectric loss is less, then sheet material is expensive, antenna cost is higher, is not suitable for popularization in enormous quantities.For the problems referred to above, applicant has researched and developed a kind of cylindrical shape multiple-input and multiple-output Yagi antenna.
Utility model content
For the problems referred to above, the utility model provides the cylindrical shape multiple-input and multiple-output Yagi antenna that a kind of cost is lower, antenna efficiency is high.
For this reason, the utility model is by the following technical solutions: cylindrical shape multiple-input and multiple-output Yagi antenna, comprise reflector plate and multiple passive director arranged in parallel, it is characterized in that, the antenna active oscillator of working in coordination with described director is set in the reflecting surface side of reflector plate, often group antenna active oscillator is made up of two copper sheets, two copper sheets are in the T-shaped shape of superposition composition, fixed by stator on the upside of it, described director is interspersed on the draw-in groove on the reflecting surface side of reflector plate by the fluting on stator, and is positioned at the periphery of described antenna active oscillator.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
Described antenna active oscillator quantity is three groups.
Described copper sheet is fixed by plastic screw, plastic nut.
Described reflector plate and stator rounded.
There is bottom described director the slot interted on reflector plate, thus can be fixed on reflector plate.
Use the utility model can reach following beneficial effect: the utility model replaces pcb board by sheet copper sheet, antenna structure is optimized again, improve antenna efficiency, reduce antenna structure size, not only significantly improve this antenna efficiency, can also significantly reduce costs, the utility model structure is simple, gain is high, is applicable to the point-to-point communication being applied to long distance.
