Polarization mismatch, realize the reliable and stable communication of high speed.For mobile-satellite terminal, such as vehicle, ship, aircraft, due to terminal
Constantly movement does not require nothing more than antenna gain height, and has extremely more limitations to the weight of antenna, section etc..The satellite reception of early stage
Terminal uses the reflector antenna of servo mechanism control, although it is special to obtain the even double-circle polarization radiation of wide bandwidth circular polarisation
Property, but section is high, heavy, is only used for large ship, train etc., is not used to trolley, aircraft etc..Wave commonly used at present
Seam guide gap aerial array, can substantially reduce antenna section.To further decrease weight and reducing cost, array-fed waveguide is used
Simultaneously metalized surface assembles for injection molding, and assembly precision requires height, and yield rate is low, and product reliability is low, and system is still deposited
The deficiencies of section is high, heavy.
Flat circle polarized array has low section, light-weighted advantage in mobile satellite communication.However, with reflecting surface day
Line, wave guide slot array antenna column are compared, and often there are feeding network complexity, the disadvantages such as loss is high, and antenna efficiency is low.Early stage antenna
Array will radiate array element and the same layout layer of feeding network, and array section is low, but feeding network loss is larger.When array element increases to one
Gain promotion after set pattern mould is offset by via net loss, is not suitable for production large scale array；Second class array by feeding network and
It being made with radiation array element layering, circuit layout is more reasonable, it can construct large-scale antenna array, but antenna array structure mistake
In complexity, feeder loss is too high, it is difficult to which production requires the aerial array of gain.
In addition, the efficiency for how improving array is also vital.On the one hand, simplify by various methods, shorten feedback
Electric network optimizes and obtains matched well characteristic, reduces the dielectric loss and conductor losses of feeding network.For high band battle array
Column close the guided wave structure radiation loss that can reduce feeding network using SIW etc.；On the other hand, array-fed net is being improved
While network efficiency, it is also that can not be ignored that especially dielectric loss, which is lost, in array element.It is only comprehensive to improve array element radiation efficiency and feedback
Electric network efficiency just can get expectation array efficiency and gain.
Summary of the invention
The shortcomings that it is an object of the invention to overcome existing flat circle polarized antenna arrays and deficiency provide a kind of efficient
The extensive circular polarised array antenna of low section.The main feed electric network of the array is located at metal floor in the following, radiation array element is located at gold
The upper surface of possession plate；Every four corner cut metal patches and a micro-strip one divide four power splitters to form a subarray, pass through metal
Gap on floor is coupled with the main feed electric network of another side, greatly simplifies feeding network, is shortened feed path, is promoted array day
The radiation efficiency of line.The array antenna structure is simple, section is low, light-weight, is suitble to the extensive high-gain circular polarisation array of building
Antenna is used for high speed satellite, mobile communication.
In order to achieve the above object, the technical scheme is that: a kind of efficient big rule of low section
Mould circular polarised array antenna, it is characterised in that: use the metal patch -102 of corner cut -101 for circular polarization radiation component, every four
Corner cut radiation patch forms a subarray -1, divides four power splitters -2 to connect with micro-strip one.Two to be connected with -201 one end of micro-strip
A patch corner cut in the same direction, two connected reversed corner cuts of the other end.Corner cut radiation patch divides four power splitters to be printed in micro-strip one
On film -3.Film -3 is bonded together by foam (or hollow dielectric-slab) -8 with metal floor -4.Micro-strip one divides four function point
Device -2 is coupled by the rectangular aperture -5 on metal floor -4 with the main feed electric network -6 of metal floor another side.Main feed electric network
Final stage is one-to-two reverse phase power splitter -7, two subarrays is motivated respectively, so that eight -102 constant amplitudes of array element of subarray -1 are same
It mutually motivates, obtains greatest irradiation in antenna surface normal direction and obtain the phases circularly polarized signals such as constant amplitude.It further increases in main feed electric network
Power splitter series and submatrix number of columns, array antenna can extend to the scale that needs, acquisition needs gain.Main feed electric network can
Using planar circuits such as integrated Medium Wave Guide or micro-strips, transmission line can also be closed using metal waveguide etc..With existing flat circle
Polarization array antenna technology is compared, and the present invention is high with the simple radiation efficiency of structure, section is low, light weight and cost is cheap and easy
In extend ultra-large array the advantages that, it is particularly suitable for movement, satellite high-speed wideband wireless communication system.
