The structure of unit 210a and 210b are substantially the same, but it is between foregoing first total 201 and second total load point 202 of load point
Connection relation it is different.In addition, those radiating elements 210a and 210b is disposed adjacent to each other, and respectively by support cylinder (not
Label) it is fixed on basal layer 10.
Furthermore, it is understood that in this present embodiment, the shape of radiating element 210a and radiating element 210b is square, and
Respectively there is one first side 211 relative to each other and a second side 212 and one the 3rd side 213 and one the 4th side relative to each other
214.But it is noted that the utility model is not limited with the shape of foregoing radiating element, such as in other embodiment,
Other geometric forms such as radiating element or rectangle or polygon.
In arrangement, as shown in the figure, the second side 212 of radiating element 210a and the second side 212 of radiating element 210b are
Adjacent to each other and facing, in other words, the first side 211 of radiating element 210a is with the first side 211 of radiating element 210b

Load point 2111, and the 4th side 214 of radiating element 210a and radiating element 210b is located at radiation cell array 200a the same sides,
And respectively there is a signal feed-in point 2141.
In this present embodiment, the angle of the signal feed-in point of radiating element 210a and radiating element 210b and its geometric center

Further to seeing, first total load point 201 is electrical by a first line 221 and one second circuit 222 respectively
The signal feed-in point 2111 of the signal feed-in point 2111 and radiating element 210b of connection radiating element 210a, and second total load point
202 are electrically connected the letter of radiating element 210a and radiating element 210b by a tertiary circuit 223 and one the 4th circuit 224 respectively

First total 201 and second total load point 202 of load point is separately available with from external the first FD feed of feed-in and
Two FD feeds.Hence, it will be appreciated that ground, first total load point 201 can be incited somebody to action by foregoing 221 and second circuit 222 of first line
First FD feed is respectively from the signal feed-in of the first side 211 of radiating element 210a and the first side 211 of radiating element 210a
2111 feed-in radiating element 210a of point can pass through foregoing tertiary circuit 223 with the total load points 202 of radiating element 210b and second
With the 4th circuit 224 by the second FD feed respectively from 2141 feed-in radiating element 210a of signal feed-in point and radiating element
210b.And it will be appreciated that the length of foregoing circuit is the transmission range that signal is transferred to radiating element from total load point.
Also, from the foregoing it will be appreciated that due in the signal feed-in point of radiating element 210a and radiating element 210b and its geometry
The angle of the heart is substantially rectangular, thus the first FD feed can enter radiation list with the second FD feed in a manner of mutually orthogonal
First 210a and radiating element 210b is resonated with generating.Additionally need prompting, the first FD feed and the second FD feed
Wavelength can it is identical can also be different, the utility model is not so limited.
In addition, in order to ensure feed-in radiating element 210a and the resonance qualitly of the signal of radiating element 210b.Radiating element
The first side 211 of 210a and radiating element 210b and the distance suggestion of the second side 212 can be about the half-wave of the first FD feed
It is long, and the distance suggestion of the 3rd side 213 and the 4th side 214 can be about the half-wavelength of the second FD feed.
Just on the whole, the radiation cell array 200a of radiating layer 20a is generally in symmetrical configuration, as shown in the figure, spoke
Cell array 200a is penetrated with a symmetrical center line S, radiating element 210a and radiating element 210b with S pairs of the symmetrical center line
Claim configuration, and tertiary circuit 223, the 4th circuit 224 are also with symmetrical center line S balanced configurations.
It will be appreciated, however, that first line 221, the second circuit 222 and first total load point 201 and symmetrical arrangements,
The position of i.e. first total load point 201 is not on the symmetrical center line S of radiation cell array 200a, but with the side of biasing
Formula is set.
The reason is that, since signal feed-in point 2111 is located at the first side 211 of away from one another couple of radiating element 210a, because
This, the first FD feed can feed-in radiating element 210a and radiating element 210b in the opposite direction.In the case, if first
Total load point 201 is located on symmetrical center line S and makes first line 221 identical with the length of the second circuit 222, then the first feed-in
Signal can cause radiating element 210a and radiating element 210b upper first simultaneously into radiating element 210a and radiating element 210b
The waveform phase difference of FD feed causes the field pattern of radiating element 210a and radiating element 210b to generate interference very in 180 degree
To the problem of offseting.Therefore, in setting, the position of first total load point 201 need to meet specified conditions, to allow first line
221 and second circuit 222 have specific length difference, and then reduce radiating element 210a and radiating element 210b between waveform do
The probability disturbed.
Specifically, in this present embodiment, 221 and second circuit 222 of first line has length difference D1, it may also be said to,
First total load point 201 is to the first signal feed-in point 2111 of radiating element 210a and the first signal feed-in of radiating element 210b
The transmission distance deviation of point 2111 is D1, and D1 is more than 0.
More particularly, the wavelength X of the transmission distance deviation D1 and the first FD feed1It need to satisfy the following conditional expression：
Conditional 1：D1=(n+1/2) × λ1× (1 ± 0.04), wherein n are the integer more than or equal to 0.
Whereby, 221 and second circuit of first line, 222 Length discrepancy, and its length difference can be approximately equal to the first FD feed
Half-wavelength odd integer multiple.Wherein, shown from experimental data, actually the length difference of 221 and second circuit 222 of first line
Can there be ± 4% feasible value between the odd integer multiple of the half-wavelength of D1 and the first FD feed.Under this arrangement, though first
The FD feed adjacent radiating element 210a of feed-in and radiating element 210b in a reverse direction, but into radiating element 210a with
The first FD feed of radiating element 210b can still keep phase that is identical or being closer to, and can avoid adjacent radiating element it
Between lead to the problem of field pattern and interfere with each other or offset.
As long as and it will be appreciated that in the opposite direction by the line length of two adjacent radiating element of signal feed-in it is poor (or
Transmission distance deviation) meet aforementioned condition formula 1, belong to the scope of the utility model.Such as in other embodiment, the second circuit
Also it is long than first line, but the difference between two circuits still meets aforementioned condition formula 1.
In addition, for second total load point 202, since signal feed-in point 2141 is respectively positioned on radiating element 210a and spoke
The 4th side 214 of unit 210b is penetrated, thus, the second FD feed can be with equidirectional feed-in radiating element 210a and radiating element
210b.But in order to ensure the antenna gain of radiating element, the 3rd line of second total 202 and the 4th side 214 of load point of electric connection
The length difference of road 223 and the 4th circuit 224 (the of i.e. second total load point 202 to radiating element 210a and radiating element 210b
The transmission distance deviation of binary signal load point 2141) suggest meeting specified conditions.
Specifically, in this present embodiment, setting 223 and the 4th circuit 224 of tertiary circuit has length difference D2, can also
It says, the transmission distance deviation of the second total load point 202 to signal feed-in point 2141 of radiating element 210a and radiating element 210b is
D2, the wavelength of the second FD feed is λ2, and D2 and λ2Satisfy the following conditional expression 2：
Conditional 2：D2=m × λ2× (1 ± 0.04), wherein m are the integer more than or equal to 0.
Whereby, the length difference of 223 and the 4th circuit 224 of tertiary circuit can be approximately equal to the second FD feed wavelength or its
Integral multiple.Wherein, shown from experimental data, actually the length difference D2 of 223 and the 4th circuit 224 of tertiary circuit and the second feed-in
Can there be ± 4% feasible value between the integral multiple of the wavelength of signal.Under this arrangement, when the second FD feed is total by second
202 feed-in radiation cell array 200a of load point, the second FD feed into radiating element 210a and radiating element 210b can
The phase for keeping identical or being closer to, generation field pattern is interfered with each other or offset between can avoiding the problem that adjacent radiating element.
In the case for this embodiment, since tertiary circuit 223 and the 4th circuit 224 are with right in radiation cell array 200a
Claim center line S balanced configurations, so tertiary circuit 223 and 224 length of the 4th circuit are generally equal, i.e., D2 is substantially equal to 0.
But the radiation cell array in the dual-polarized antenna structure of the utility model also can be in symmetrical arrangements, such as in other embodiment
In, tertiary circuit is also long than the 4th circuit, but between tertiary circuit and the 4th circuit length difference (i.e. second total load point with
The transmission distance deviation of those secondary signal load points of radiating element) still meet aforementioned condition formula 2.
