Detailed Description
The dual-polarized low-profile micro base station antenna and the array antenna provided by the invention are further described in detail with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims.
Example one
As shown in fig. 1, the dual-polarized low-profile micro base station antenna provided by the present invention includes: radiation unit 1, power distribution board 2, reflecting plate 3. The radiation unit 1 is connected to a power distribution plate 2, and the power distribution plate 2 is provided on the front or back surface of the reflection plate 3. .
Specifically, as shown in fig. 2. The radiating element 1 comprises a first radiating layer 101 and a second radiating layer 102, wherein the first radiating layer 101 is coupled to the second radiating layer 102 in a feeding mode. The first radiation layer 101 is provided with a first feeding point 1012 and a second feeding point 1013, the first feeding point 1012 and the second feeding point 1013 are distributed in axial symmetry and the feeding form is direct feeding.
The second radiation layer 102 is made of an aluminum sheet, four trapezoidal seams 1021 are formed in the second radiation layer 102, four welding grooves 1011 are formed in the first radiation layer 101, the positions of the four welding grooves are opposite to the trapezoidal seams 1021, and a metal support piece 1022 is welded to each welding groove 1011 and connected with the second radiation layer 102. The metal supporting piece 1022 is formed by stamping a metal plate on the second radiation layer 102, and on one hand, plays a role in supporting the second radiation layer 102; on the other hand, the one-time SMT assembly is facilitated, and the one-time intermodulation yield of the antenna is improved. In the embodiment, four trapezoidal seams 1021 are formed on the second radiation layer 102, but the invention is not limited to this, and other numbers of trapezoidal seams 1021, such as 3, 5, etc., may be formed according to practical situations.
The second radiation layer 102 is square, each trapezoidal seam 1021 is an equilateral trapezoidal seam, and four trapezoidal seams 1021 are distributed in a square shape. The central axes of the two trapezoidal seams 1021 are superposed with the horizontal central axis of the second radiation layer 102 and are symmetrically distributed about the vertical central axis of the second radiation layer 102; the central axes of the other two trapezoidal seams 1021 are coincident with the vertical central axis of the second radiation layer 102 and are symmetrically distributed about the horizontal central axis of the second radiation layer 102; the bottom edges of the two trapezoidal seams 1021 which are distributed in the axial symmetry manner are arranged oppositely, that is, the upper bottom edges of the two trapezoidal seams 1021 which are distributed in the axial symmetry manner are arranged oppositely, and the lower bottom edges are arranged oppositely; or the lower bottom edges of the two axisymmetric trapezoidal seams 1021 are oppositely arranged, and the upper bottom edges are oppositely arranged. The trapezoidal seam 1021 is arranged on the second radiation layer 102, so that the size of the antenna can be reduced, and when the antenna is used for a same-frequency antenna, the different-row same-polarization isolation of the same-frequency antenna can be improved.
The trapezoidal slit 1021 can be arranged in the following manner in addition to the above-described arrangement: as shown in fig. 3, wherein the central axes of the two trapezoidal seams 1021 are coincident with the first diagonal of the second radiation layer 102 and symmetrically distributed about the second diagonal of the second radiation layer 102; while the central axes of the other two trapezoidal seams 1021 are coincident with the second diagonal of the second radiation layer 102 and symmetrically distributed with respect to the first diagonal of the second radiation layer 102. Similarly, the bottom edges of two trapezoidal seams 1021 symmetrically distributed about the diagonal of the second radiation layer 102 are arranged opposite to each other; accordingly, the position of the solder recess 1011 on the first radiation layer 101 opposite to the position of the trapezoidal slit 1021 is adjusted accordingly.
The shape of the first radiation layer 101 and the second radiation layer 102 may be any one of a square, a circle, an octagon, and other polygons according to actual needs.
The power distribution plate 2 is made of a printed circuit board, as shown in fig. 4. The power distribution board 2 comprises a first feeding port 201, a second feeding port 202, a third feeding port 203, a fourth feeding port 204, a fifth feeding port 205 and a sixth feeding port 206, wherein the first feeding port 201, the second feeding port 202 and the third feeding port 203 form a feeding path; and the fourth feed port 204, the fifth feed port 205, and the sixth feed port 206 constitute another feed path.
The electrical length of the second feeding port 202 is greater than the electrical length of any one of the first feeding port 201 and the third feeding port 203, and the second feeding port 202 is an inverted feeding port. When the input power of the first feeding port 201 is equal to the input power of the second feeding port 202, and the input power of the third feeding port 203 is equal to 1:2:1, the influence of the high-order mode of the antenna on the antenna can be counteracted; when the antenna is used for the same-frequency antenna, the isolation of the antennas in the same column can be greatly improved.
Because the reduction of the height of the antenna can narrow the impedance bandwidth of the antenna, the invention reduces the height of the antenna and simultaneously arranges a multistage matching network on the power distribution board 2 to improve the impedance bandwidth of the antenna. The multi-stage matching network is formed by a fourth feeding port 204, a fifth feeding port 205 and a sixth feeding port 206 as another feeding path. By modifying the feed path, bandwidth matching can be achieved.
The antenna provided by the present invention, through optimization of the radiation unit 1 and the power distribution board 2, reduces the height of the antenna, which is shown in fig. 5, and reduces 0.25 wavelength under the conventional structure to the height of 0.08 wavelength, which can be expressed as h ═ 0.08 λ, where λ ═ C/f, C represents the speed of light, and f represents the center frequency of the antenna operation. The invention reduces the height of the antenna as a whole and effectively reduces the size of the antenna.

The co-frequency antenna comprises a left antenna and a right antenna, and for convenience of observation and explanation, the two antennas are arranged in a transverse manner as shown in fig. 6.

The double-row same-frequency antenna can work between frequency bands of 3.4 GHz-3.6 GHz, and by taking the working frequency band as an example, simulation tests are carried out on standing-wave ratio, isolation, horizontal plane and vertical plane beam width, horizontal plane cross polarization ratio and gain of a row of antennas in the double-row same-frequency antenna. As shown in fig. 7, the standing-wave ratios of the two polarization ports of the same-frequency antenna are both less than 1.5, which indicates that the antenna is well matched in the frequency band range of 3.4GHz to 3.6 GHz. As shown in fig. 8, the isolation of the two polarization ports of the same-frequency antenna is greater than 23dB, which indicates that the antenna has good isolation in the frequency band range of 3.4GHz to 3.6 GHz.

As shown in fig. 10, the axial cross polarization ratio of the same-frequency antenna is greater than 20dB, and the sector cross polarization ratio is greater than 10dB, which indicates that the antenna has a good horizontal cross polarization ratio in the frequency band range of 3.4GHz to 3.6 GHz. As shown in fig. 11, the gain of the antenna is greater than 11.95dB, and the gain of the antenna after the operating frequency is greater than 3.52GHz tends to increase, indicating that the gain of the antenna is good in the frequency band range of 3.4GHz to 3.6 GHz. And under the same working frequency band, the simulation effect of the other row of antennas is similar.
