Description
Technical field
A kind of ultra-wideband Bipolarization antenna for base station of 2G/3G/4G tracking exchages of the present invention refers to communication base station
Antenna.
Background technology
With the fast development of wireless communication technique, the case where a variety of communication standards exist simultaneously, has become certainty.Another party
Face, since people are to the worry of aerial radiation and the conflict of original base station location so that the addressing of new antenna for base station is increasingly difficult to,
To antenna for base station, more stringent requirements are proposed for major operator simultaneously, therefore, designs and can adapt to more multi-standard, covering frequency range
Broader antenna for base station can efficiently solve the problem of base station selection, save vast resources and cost of building a station.Frequency range 1700 ~
2700MHz completely covers a variety of communication standards of three big operators（DSC1800,3G and 4G whole frequency range）, however, such wide
Frequency band in, antenna for base station keeps good circuit parameter and radiation parameter index, is the difficult point of design.It is therefore necessary to design
Go out a kind of new antenna for base station to meet actual use demand.
Invention content
The present invention is directed to the demand, provides a kind of ultra-wideband double-polarized base station day of 2G/3G/4G tracking exchages
Line can provide one kind and being suitable for multiple types, the broader base station of covering frequency range not being added to this in the case of significantly
Antenna and the consistency for keeping indices.
A kind of ultra-wideband Bipolarization antenna for base station of 2G/3G/4G tracking exchages includes reflecting plate, radiating element and n shapes
Bending；
The reflecting plate cross section is U-shaped, and the bottom surface of reflecting plate is plane, and both sides are side.
The side on the both sides of the reflecting plate is perpendicular to bottom surface, and two sides are contour.
It is provided with three on the inside of reflecting plate to be mutually parallel and the bending of equidistant n shapes, wherein one in reflecting plate
On heart line, the height of n shapes bending is not higher than the height of reflecting plate side.
The N-shaped bending can effectively improve front and back ratio, astringent lotion plane lobe width, and N-shaped is bent by electromagnetism
The discontinuous barrier of wave spatially, while in different operating frequency band, thus it is possible to vary its size is comparatively ideal front and back to obtain
Than with convergent horizontal lobe width.
It is both provided with multiple equidistant radiating elements in every interspace between the bending of n shapes.
It is interlaced arrangement between the radiating element being arranged in two interspaces between the bending of n shapes, between reduction radiating element
It intercouples to improve the isolation of antenna.
Middle between radiating element is provided with fastener, and the isolation board with reflecting plate plane perpendicular is equipped on fastener, and
Angle between isolation board and the bending of n shapes is also 90 °, and comparatively ideal friendship can be obtained by the size and position that optimize isolation board
Pitch polarization ratio.
The fastener is plastics fastener.
Present inventive concept is ingenious, simple in structure, using effect is good, and ultra-wideband Bipolarization antenna for base station of the invention is by two
Row radiating element is staggered so that isolation reaches 30dB or more, is not increasing reflection board size and radiating element pattern
In the case of radiate front and back ratio 30dB or more can be improved, horizontal plane half-power beam width converges within ± 5 °, cross polarization ratio
It significantly improves, and of low cost, is readily produced and safeguards.
