Description
Technical field
This utility model belongs to antenna technical field, and in particular to the panel antenna array that a kind of multi-beam is pointed to.
Background technology
In prior art, the radio such as communication, radar, navigation, broadcast, TV is passed by radio wave
Information is passed, the radiation and reception of radio wave is required for.In radio, for radiating and receiving radio wave
Device is referred to as antenna.Antenna is the coupling required for providing between transmitter or receiver and the medium for propagating radio wave.My god
Line is as transmitter, receiver, and an important component part of radio.
In mobile communication, point-to-point antenna is usually used reflector antenna, can only realize simple beam high-gain.Point is right
Multiple spot and point-to-area antenna are usually used base-station antenna array, usually eight yuan or ten six-element antennas composition linear array, to one
Terminal in individual covering of the fan such as mobile phone is covered.But this is the antenna of two kinds of different structures and function, it is impossible to which enough fusions are shared.
Utility model content
In order to solve the above-mentioned problems in the prior art, this utility model provides the flat board that a kind of multi-beam is pointed to
Aerial array.
The technical problems to be solved in the utility model is achieved through the following technical solutions：
The panel antenna array that a kind of multi-beam is pointed to, the array that plate aerial is divided into M*N, the array include
M*N panel antenna unit, and each described panel antenna unit includes multiple terminal radiation units, each described plate aerial
The input port of unit is connected with the phase shifter, and each described phase shifter is cascaded to a total input port by power splitter.
Further illustrate as of the present utility model, the phase shifter phase place is identical, panel antenna array is overall in the same direction, shape
Into a wave beam.
Further illustrate as of the present utility model, the phase shifter phase place is different, panel antenna array is overall not in the same direction,
Multiple panel antenna units were distributed with out of phase by the phase shifter, formed the wave beam of multiple different directions.
Further illustrate as of the present utility model, the terminal radiation unit adopts rectangular waveguide opening horn structure.
Further illustrate as of the present utility model, the panel antenna array is applied to the frequency model of 1GHz-100GHz
In enclosing
Compared with prior art, the beneficial effect of this utility model acquirement is：
Plate aerial is divided into this utility model the array of M*N, and each panel antenna unit is followed by the phase shifter and is formed
Multibeam antenna, can either realize single wave beam high-gain point-to- point communication, can realize the larger region of multi-beam antenna again, because
This both can be used for relay wireless signals transmission and available base stations and the point-to-multipoint of terminal covered.
This utility model is described in further details below with reference to drawings and Examples.
Description of the drawings
Fig. 1 is the panel antenna array structural representation that a kind of multi-beam of the present utility model is pointed to.
Fig. 2 is the tree-shaped work(separation structure schematic diagram of panel antenna array that a kind of multi-beam of the present utility model is pointed to.
Fig. 3 is that the array terminal radiative unit structure of the panel antenna array that a kind of multi-beam of the present utility model is pointed to shows
It is intended to.
Specific embodiment
Technological means and effect that predetermined purpose is taken is reached for this utility model is expanded on further, below in conjunction with accompanying drawing
And embodiment is to specific embodiment of the present utility model, architectural feature and its effect, describe in detail as follows.
As shown in figure 1, the panel antenna array structural representation that a kind of multi-beam of the present utility model is pointed to, by flat board day
Line is divided into the array of M*N, and array includes M*N panel antenna unit, and each panel antenna unit includes multiple terminals
Radiating element, the input port of each panel antenna unit are connected with the phase shifter, and each phase shifter is by power splitter with tree-shaped work(
Separation structure is cascaded to a total input port, as shown in Figure 2.
Phase shifter phase place is identical, and panel antenna array is overall in the same direction, forms a wave beam；Phase shifter phase place is different, flat board
Aerial array is overall, and multiple panel antenna units were distributed with out of phase by the phase shifter not in the same direction, formed multiple differences
The wave beam in direction；Terminal radiation unit adopts rectangular waveguide opening horn structure, as shown in Figure 3.
In 5G communications, because very big to data traffic requirement, network speed requires that up-downgoing speed is very high very soon, this
Require to use millimeter wave frequency band as main communication frequency band.In millimeter wave frequency band, the unit volume meeting very little of antenna, space
Loss is big, transmission range also can relative proximity, therefore the spacing of wireless base station is all in the range of 150-300 rice.In this application
Under environment, millimeter wave antenna array is divided into multiple submatrixs, such as M*N submatrix.
Each panel antenna unit is followed by the phase shifter, and when the phase shifter, phase place was identical, whole antenna array in the same direction, will be formed
One high-gain wave beam, realizes signal transmission between remote base station.When adjacent several phase shifter phase places are according to some phase place
During difference arrangement, these submatrixs will form a beamlet in one direction, and whole front can shape in different directions simultaneously
Into beamlet, different terminal locations are covered.
Above content is with reference to specific preferred implementation further detailed description of the utility model, it is impossible to
Identification is of the present utility model to be embodied as being confined to these explanations.Ordinary skill for this utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should be all regarded
For belonging to protection domain of the present utility model.
