Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention further describes.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and without
In the restriction present invention.
Refering to Fig. 1～Fig. 3, the meandered antenna array of the embodiment of the present invention includes the multiple of setting on substrate 10 and substrate 10
Independently feed, identical element antenna, multiple element antennas include a center antenna 21 and conllinear with center antenna 21
And it is symmetrically set in row's outer antennas 22 of center antenna 21 both sides；Substrate 10 is flexible, and centered on center antenna 21
Towards back side bending, outer antennas 22 are made to be symmetrically positioned in the both sides of substrate 10 curved surface.
Spacing between spacing between center antenna 21 and the outer antennas 22 closing on, adjacent two outer antennas 22
It is 1/4, the i.e. l/4 of the operating frequency wavelength l of aerial array, imitated with the superposition that adjacent two element antenna is better achieved
Really.
As Fig. 1, in order to aerial array mode is better described, in the present embodiment, outer antennas 22 only have a row, and symmetrically
Centrally disposed antenna 21 both sides.In other embodiments, multiple element antennas also include multiple rows of outer antennas 22, often exclusive
Enclose antenna 22 parallel with this row's outer antennas 22 positioned at center described above, finally, all of outer antennas 22 are with center
Array setting centered on antenna 21, and the spacing between two adjacent outer antennas 22 is consistent.Further preferably adjacent two
Spacing between row's outer antennas 22 is also the 1/4 of the operating frequency wavelength of aerial array.
The substrate 10 of antenna is soft bendable material, such as the circuit board of pvc material or antenna-mounted substrate.Element antenna
The antenna of high directivity, group for high gains such as high-gain bar antenna, spring type metal antenna or ceramic dielectric bar antennas
Element antenna performance after conjunction will not change (even if change is also negligible) substantially, is equivalent to the gain of several antennas after combination
Effect that is constant and changing with substrate bending after Directionality levels superposition.Each element antenna independent power feeding, then passes through rear end
Circuit does coupling again and integrates, and can reduce impedance matching difficulty and the precision between antenna well.
As shown in Fig. 2 before non-curved substrate 10, produce respectively between the center antenna 21 that is arranged side by side, outer antennas 22
The raw bar-shaped radiation scope perpendicular to substrate 10；As shown in figure 3, after substrate 10 is bent to form certain curvature, fixing base
Plate 10 is changed with preventing deformation.The directional diagram radiation scope that center antenna 21, outer antennas 22 are formed is wider, and convergence 1/4 is spherical.
Because between two adjacent element antennas, spacing is equal, the angle between two neighboring radiation scope is identical, and radiation is uniformly.
In order to improve the easy composite behaviour of aerial array, substrate 10 is provided with array and supplies corresponding element antenna respectively
The antenna installation position of insertion, such as slot, each antenna installation position external feed source respectively.Element antenna is installed to corresponding sky
Behind line installation position, element antenna is naturally connected with feed source and is added in aerial array, and disassembly process is also very convenient.
As seen in Figure 3, directional diagram is not preferable circular arc, the weight of the adjacent directional diagram of two element antennas
Folded place is recessed, and when element antenna negligible amounts, depression is especially apparent.The corresponding directional diagram of element antenna is because base
The bending of plate and change, when the element antenna number in straight line section increases, the figure of its general direction figure is to circle
Ball is drawn close.And depending on the angle of bend of substrate is with element antenna quantity and use demand, need to radiate wider array of face, then bend journey
Degree just should increase (i.e. radius of curvature should diminish)；Radiation scope need diminish, then degree of crook just should reduce (i.e. radius of curvature should
Increase).As shown in Figure 4 and Figure 5, it is a kind of sky after adding unit antenna amount on the basis of the embodiment shown in Fig. 1～3
Linear array and its directional diagram, center antenna 21 is straight with what row outer antennas 22 conllinear with center antenna 21 placed in the middle were located
Line both sides are symmetrically arranged with some row's element antennas, and often row's element antenna is parallel with row's outer antennas 22 placed in the middle, all includes
The symmetrically arranged outer antennas of one center antenna 21 and center antenna 21 both sides 22 at middle part, on each row and every string, phase
Adjacent center antenna 21 and center antenna 21, center antenna 21 and outer antennas 22, outer antennas 22 and outer antennas 22 spacing
All equal, preferably l/4.Finally, string center antenna 21 is located on the folding line at substrate 10 middle part, and outer antennas 22 are curved with this
Symmetrical centered on broken line (as Fig. 4).As can be seen that in the case that there is equal radiation scope, its recess size
Less, directional diagram more convergence 1/4 is spherical.
Another object of the present invention is to providing a kind of method for arranging of meandered antenna array, comprising:
One substrate 10 is provided；
Arrange center antenna 21 on the substrate 10；
Arrange outer antennas 22 in the Peripheral-array of center antenna 21；
Centered on center antenna 21, substrate 10 is bent to predetermined curvature.
Wherein, when arranging different aerial arrays in addition it is also necessary to substrate 10 curved surface is adjusted according to different radiation demands
The quantity of the outer antennas 22 of both sides, and accordingly adjust the curvature of substrate 10.
By the present invention in that adjust the directional diagram of aerial array with the method bending substrate, the making of aerial array and making
Simple with method, it is possible to achieve independent assortment, based on the degree of crook that can arbitrarily adjust substrate, the directional diagram of whole array can
To be adjusted at any time according to real-time requirement, and method of adjustment is simply easily realized.Bar-shaped by using several identical high-gains
, as element antenna, the element antenna performance after combination will not change substantially, group for the high gains such as antenna and the antenna of high directivity
The gain being equivalent to several antennas after conjunction constant and with the effect of substrate bending change after Directionality levels superposition；Each unit
Antenna is configured to independent power feeding, can do coupling again by back-end circuit and integrate, reduce the impedance between antenna after feed
Join difficulty and precision.In addition, also the number of element antenna can be increased and decreased to reach communication requirement, practicality according to actual requirement
By force.
The above is only the specific embodiment of the application it is noted that ordinary skill people for the art
For member, on the premise of without departing from the application principle, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as the protection domain of the application.
