Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
As shown in Fig. 1～2, the antenna element 1 of the present invention, it is mountable on metallic reflection plate (non-label, lower same), is used for
Launch and receive communication signal.
Described antenna element 1 includes antenna element main body 10 and the dielectric ring 20 arranged bottom antenna body 10.Institute
State antenna element main body 10 and include radiant body 110 and supporting spokes beam 110 feed Balun 120 for its feed, described medium
Ring 20 is arranged around the lower end of described feed Balun 120, and the dielectric constant of described dielectric ring 20 is 6～20.
For the base station antenna unit of conventional symmetrical dipole type, the height of its oscillator surface distance metallic reflection plate
Generally 1/4 operation wavelength, the i.e. height of feed Balun is 1/4 operation wavelength.When height is less than 1/4 operation wavelength
Time, metallic reflection plate will be very violent to the near field reflections of antenna element, thus causes the impedance variation of antenna element acutely, resistance
Anti-bandwidth is deteriorated.The antenna element 1 that the present invention provides is added by loaded medium ring 20 equivalence between radiant body 110 and reflecting plate
Distance between long described radiant body 110 and reflecting plate, effectively reduces the section height of antenna element 1 to 1/6 operation wavelength
Hereinafter, even if the height of feed Balun 120 is less than 1/6 operation wavelength, the space shared by antenna cost and antenna is saved, it is achieved
The miniaturization antenna for base station of low section.
Meanwhile, on the premise of not increasing antenna element area, loaded medium ring 20 can reduce the resonant frequency of antenna, supports
Disappear and move in the resonant frequency caused because oscillator section height reduces, and due to the equivalent electric length of oscillator surface distance reflecting plate
Increase, thus weaken the phenomenon of the impedance bandwidth variation that base plate (i.e. metallic reflection plate) reflection causes, it is ensured that circuit parameter and spoke
Penetrate performance parameters stable, so that all kinds of actually used base station that described antenna element 1 is applicable to including smart antenna
Antenna.
During it should be noted that the dielectric constant of dielectric ring 20 takes between 6～20, it is possible to ensure that it plays equivalence and increases spoke
Beam 110 and the effect of the height of reflecting plate, meanwhile, prevent from weakening the gain of described antenna element 1 and to antenna entirety
Impedance bandwidth produces impact, the impedance bandwidth good to guarantee antenna.
It addition, generally, feed Balun 120 not only plays support and feed effect, also acts as certain impedance transformation
Effect, therefore, is actually placed on feed bar by described dielectric ring 20 around the surrounding being fixed on described feed Balun 120
The outside of human relations 120, it is possible to decrease the impact of described dielectric ring 20 feed structure internal on feed Balun 120.

Actual height can design according to the antenna for base station optimization of the dielectric ring 20 of required loading.
Preferably, the width of described dielectric ring is less than 1/2 times of operation wavelength.In the present invention, the reality of described dielectric ring 20
Border width can design according to the antenna for base station optimization of required loaded medium ring 20.
By height and the width of the dielectric ring 20 of reasonable design high-k, each of this antenna element 1 can be made
Item radiation parameter meets the requirement of antenna for base station.
Alternatively, the rotationally symmetric polygonal ring shape or circular of described dielectric ring 20.Usually, described feedback
Electricity balun 120 includes that support column, described support column upper end connect with radiant body 110, so that described feed Balun realizes feed
Effect, lower end is fixed on described reflecting plate, therefore, described dielectric ring 20 is designed as polygonal ring shape or circular, can keep away
Open the support column of feed Balun 120 in antenna element 1 and described dielectric ring 20 is easily installed.
Preferably, the geometric center of described dielectric ring 20 and the throwing on reflecting plate of the geometric center of antenna element main body 10
Shadow overlaps.
Preferably, described radiant body 110 includes two secondary orthogonal symmetrical dipoles (non-label, lower same), described every secondary symmetrical
Oscillator includes two radiation arms being in same level.
Described two secondary symmetrical dipoles are with the mutually orthogonal overall knot installing one relation that is centrosymmetric of formation of polarised direction
Structure, described every secondary symmetrical dipole in the same plane by two and arrange about same axisymmetrical radiation arm (non-label,
Lower same) composition, each described radiation arm structure is identical, and is installed on the same plane of reference (being parallel to reflecting plate), constitutes a spoke
Penetrate face (namely above-mentioned oscillator surface).
Moreover, it relates to a kind of antenna for base station (not shown) using above-mentioned antenna element.Above-mentioned owing to using
Antenna element, it has the lowest, the feature that volume is little.
In sum, the antenna element 1 that the present invention provides effectively drops by using the dielectric ring 20 of high dielectric constant material
The section height of low antenna element, to below 1/6 operation wavelength, is advantageously implemented the miniaturization of antenna for base station: on the one hand, institute
State dielectric ring and the resonant frequency of antenna on the premise of not increasing conventional aerial cellar area, can be reduced, offset because oscillator cuts open
Move in the resonant frequency that face height reduction causes, and, owing to the equivalent length of oscillator surface with reflecting plate increases, thus weaken anti-
Penetrate the phenomenon of the impedance bandwidth variation that plate reflection causes.On the other hand, by the size of appropriate design high dielectric constant ring
And shape, every radiation parameter of described antenna element can be made to meet the requirement of antenna for base station.
The above is only the some embodiments of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
