Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A dual polarized antenna 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings. As shown in fig. 1 to 24, a dual polarized antenna 1 according to an embodiment of the present invention includes a radiation element 10, a first feed element 20, a second feed element 30, and a reflection plate 40.
As shown in fig. 1 to 24, the radiation element 10 of the dual polarized antenna 1 according to the embodiment of the present invention includes a horizontally polarized antenna element 101 and a vertically polarized antenna element 102.
The horizontally polarized antenna unit 101 is annular, the horizontally polarized antenna unit 101 has a first slot 1011, and the horizontally polarized antenna unit 101 has a closed outer circumference 1012 and a closed inner circumference 1013 defined by the first slot 1011, i.e. the edge of the first slot 1011 is the inner circumference 1013 of the horizontally polarized antenna unit 101. The vertically polarized antenna element 102 is ring-shaped, the vertically polarized antenna element 102 has a second slot 1021, the vertically polarized antenna element 102 has a closed outer circumference 1022 and a closed inner circumference 1023 defined by the second slot 1021, i.e. the edge of the second slot 1021 is the inner circumference 1023 of the vertically polarized antenna element 102.
Wherein, the horizontal polarization antenna unit 101 and the vertical polarization antenna unit 102 are arranged crosswise in a cross shape. The first feed element 20 cooperates with the horizontally polarized antenna element 101 and the second feed element 30 cooperates with the vertically polarized antenna element 102. The reflection plate 40 is provided below the horizontally polarized antenna element 101 and the vertically polarized antenna element 102. In other words, horizontally polarized antenna element 101 and vertically polarized antenna element 102 are provided above reflecting plate 40.
The radiating element of the existing dual-polarized antenna comprises two dipole antennas, each comprising two arms, i.e. the radiating element of the existing dual-polarized antenna comprises four arms. Wherein, two arms of each dipole antenna are not directly connected, and then the two dipole antennas are not crossed, and each arm can not work alone, and can only work normally when forming a dipole antenna.
Furthermore, each arm is provided with a slot, but since the two arms of each dipole antenna are not directly connected, the slots of the two arms of each pair of dipole antennas are independent of each other and cannot communicate with each other. Furthermore, the slot of each arm may have at least one opening out, i.e. the slot is not closed.
Furthermore, the feeding system of the existing dual-polarized antenna including two dipole antenna elements must adopt a robert balun structure or a modified structure of the structure.
In the existing dual-polarized antenna, each dipole antenna element has a horizontal symmetry axis along which the current direction and the main polarization direction of the electric field of one arm are directed from the outside of the dual-polarized antenna to the middle of the dual-polarized antenna (i.e., the portion between the two arms), and along which the current direction and the main polarization direction of the electric field of the other arm are directed from the middle of the dual-polarized antenna to the outside of the dual-polarized antenna. That is, the main polarization direction of the electric field of one dipole antenna element is consistent with the current direction of the other dipole antenna element, the current directions of the two arms are consistent, the main polarization direction of the electric field of the two arms is consistent, and the current direction of the two arms and the main polarization direction of the electric field of the two arms are both directed from one end of the horizontal symmetry axis to the other end of the horizontal symmetry axis.
Therefore, the existing dual-polarized antenna has the defects of small radiation range and limited bandwidth, and cannot realize wider bandwidth. The main polarization direction of the electric field of the director needs to be consistent with the main polarization direction of the electric field of the dipole antenna unit, so that the normal operation of the dual-polarized antenna is ensured and the related technical requirements are met. In order to achieve the above purpose, the dipole antenna elements of the existing dual-polarized antenna are arranged in parallel with the directors, so that the arrangement mode of the directors is limited.
Since the horizontally polarized antenna element 101 of the radiation element 10 of the dual-polarized antenna 1 according to the embodiment of the present invention has the first closed slot 1011 and the vertically polarized antenna element 102 has the second closed slot 1021, and the horizontally polarized antenna element 101 and the vertically polarized antenna element 102 are arranged crosswise, the radiation element 10 of the dual-polarized antenna 1 according to the embodiment of the present invention is completely different from the existing dual-polarized antenna.
Specifically, the radiation principle of the radiation unit 10 is: the horizontally polarized antenna element 101 has a horizontal symmetry axis (i.e., the first longitudinal symmetry axis L1), and the current of the horizontally polarized antenna element 101 is mainly concentrated on both sides of the horizontally polarized antenna element 101 and the portion where the loop connects with the first slot 1011, and the main current direction is indicated by the solid arrows in fig. 16. The electric field of the horizontally polarized antenna element 101 is mainly concentrated in the groove-like structure (first slot 1011) portion of the horizontally polarized antenna element 101, and the dashed arrow in fig. 16 (for distinction from the solid arrow) indicates the main polarization direction of the electric field. By comparison, it can be seen that the current direction of horizontally polarized antenna element 101 does not completely coincide with the electric field main polarization direction, and the electric field main polarization direction of horizontally polarized antenna element 101 is perpendicular to the direction of the horizontal symmetry axis of horizontally polarized antenna element 101. The radiation principle of the vertically polarized antenna element 102 is the same as that of the horizontally polarized antenna element 101.
More importantly, each of horizontally polarized antenna element 101 and vertically polarized antenna element 102 is a loop-slot antenna element, and each of horizontally polarized antenna element 101 and vertically polarized antenna element 102 is fitted with a feed element, so that each of horizontally polarized antenna element 101 and vertically polarized antenna element 102 can be operated independently (independently operated).
Since the radiation principle of the radiation element 10 is completely different from that of the radiation element of the existing dual-polarized antenna. Therefore, the dual-polarized antenna 1 and the radiating elements 10 thereof according to the embodiment of the present invention have higher gain and wider frequency band, and greatly improve the technical index values of the dual-polarized antenna 1 and the radiating elements 10 thereof (for example, achieve better port isolation, better cross polarization index, etc.).
According to the dual-polarized antenna 1 and the radiation unit 10 thereof of the embodiment of the invention, the horizontal polarization antenna unit 101 having the closed first slot 1011 and the vertical polarization antenna unit 102 having the closed second slot 1021 are arranged, and the horizontal polarization antenna unit 101 and the vertical polarization antenna unit 102 are arranged in a crossed manner, so that higher gain and wider frequency band can be achieved, and technical index values (for example, better port isolation degree, better cross polarization index and the like) of the dual-polarized antenna 1 and the radiation unit 10 thereof are greatly improved.
Moreover, because the radiation principle of the radiation unit 10 is different from that of the radiation unit of the existing dual-polarized antenna, the dual-polarized antenna 1 according to the embodiment of the present invention does not need to use only the robert balun for feeding, and a director can be arranged along the main polarization direction of the electric field, so that the structure of the dual-polarized antenna 1 according to the embodiment of the present invention is more flexible, and the dual-polarized antenna 1 is easier to perform performance and index optimization.
Therefore, the dual-polarized antenna 1 and the radiating unit 10 thereof according to the embodiment of the present invention have the advantages of higher gain, wider frequency band, large radiation range, better port isolation, better cross polarization index, more flexible structure, easier performance and index optimization, and the like.
The working frequency range of the dual-polarized antenna 1 can reach 1.7GHz-2.7GHz, the polarization modes are + 45-degree polarization and-45-degree polarization dual polarization, the gain can reach 9.5dB, the beam width can reach 60-65 degrees, the input impedance is 50 omega, the standing wave can be less than 1.5, and the isolation can reach 30 dB.
The dual polarized antenna 1 according to the embodiment of the present invention may be a V/H (vertical/horizontal) polarized antenna, and may also be a ± 45 ° polarized antenna.
As shown in fig. 1 to 24, a dual polarized antenna 1 according to some embodiments of the present invention includes a radiation element 10, a first feed element 20, a second feed element 30, a reflection plate 40, a first director 50, a second director 60, a load plate 70, and a dielectric plate (not shown in the drawings).
Each of the radiation element 10, the first feeding element 20, and the second feeding element 30 is provided or formed on a dielectric plate. Specifically, each of the radiation element 10, the first power feeding element 20, and the second power feeding element 30 may be a metal sheet provided on the dielectric plate or a metal layer formed on the dielectric plate.
The horizontally polarized antenna element 101 is annular, the horizontally polarized antenna element 101 having a first slot 1011, the horizontally polarized antenna element 101 having a closed outer periphery 1012 and a closed inner periphery 1013 defined by the first slot 1011. The vertically polarized antenna element 102 is annular, the vertically polarized antenna element 102 having a second slot 1021, the vertically polarized antenna element 102 having a closed outer periphery 1022 and a closed inner periphery 1023 defined by the second slot 1021.
Each of the horizontally polarized antenna element 101 and the vertically polarized antenna element 102 may be composed of two oppositely disposed loop-slot antenna elements. The two loop-slot antenna units are directly connected and structurally integrated. The structural integration here means that the two loop-slot antenna units are integrally connected (for example, integrally formed or welded), and it is structurally difficult to clearly divide the structure position of a single loop-slot antenna unit.
It is because the four loop-slot antennas are connected two by two to form a whole, and thus the horizontal polarization antenna element 101 and the vertical polarization antenna element 102 are formed to have a cross-shaped structure and a cross point (the cross point may be in the central portion or in another position deviating from the central portion), and the cross point position separates the horizontal polarization antenna element 101 and the vertical polarization antenna element 102 in a manner of distinguishing upper and lower layers, and is not connected to each other.
The inside of each loop-slot antenna unit has an aperture, and the apertures in the two loop-slot antenna units are connected to each other to form a whole, i.e. the first slot 1011 and the second slot 1021.
Horizontal polarization antenna element 101 may be a flat plate, vertical polarization antenna element 102 may be a flat plate, and horizontal polarization antenna element 101 and vertical polarization antenna element 102 may be located on the same plane (horizontal plane). A through-groove is provided in a side surface of one of horizontally polarized antenna element 101 and vertically polarized antenna element 102, and the other of horizontally polarized antenna element 101 and vertically polarized antenna element 102 passes through the through-groove. Further, horizontally polarized antenna element 101 and vertically polarized antenna element 102 may be located on different planes (horizontal planes).
For example, the through-slot is provided on each of the first and second opposite side surfaces of the horizontally polarized antenna element 101, and the vertically polarized antenna element 102 includes a first portion and a second portion. The end of the first portion passes through the through slot on the first side and into the first slot 1011, the end of the second portion passes through the through slot on the second side and into the first slot 1011, and the end of the first portion is connected (e.g. welded) to the end of the second portion.
Horizontal polarization antenna element 101 may be a flat plate, vertical polarization antenna element 102 may be a flat plate, and horizontal polarization antenna element 101 and vertical polarization antenna element 102 may be located on different planes.
As shown in fig. 15-17, the horizontally polarized antenna element 101 includes a first body 1014, the vertically polarized antenna element 102 includes a second body 1024, the first body 1014 lies on a first plane, and a portion 1026 of the second body 1024 intersecting the first body 1014 protrudes with respect to the remaining portion of the second body 1024 so as to form a channel (or groove) for avoiding the first body 1014, the remaining portion of the second body 1024 lying on the first plane.
Alternatively, the second body 1024 lies on a first plane, and a portion of the first body 1014 intersecting the second body 1024 protrudes relative to the remainder of the first body 1014, which lies on the first plane, so as to form a channel (or groove) for avoiding the second body 1024.
In addition, a through slot is provided on a side surface of one of the first body 1014 and the second body 1024, and the other of the first body 1014 and the second body 1024 passes through the through slot.
As shown in fig. 18, the horizontally polarized antenna unit 101 includes a first body 1014 and a first protrusion 1015, the first protrusion 1015 is connected to the first body 1014 and protrudes relative to the first body 1014, the first protrusion 1015 is configured into an elbow shape, wherein the first body 1014 and the first protrusion 1015 define a first slot 1011.
As shown in fig. 19, the vertically polarized antenna unit 102 includes a second body 1024 and a second projection 1025, the second projection 1025 being connected to the second body 1024 and projecting with respect to the second body 1024, the second projection 1025 being configured in a bent shape. Wherein the second body 1024 and the second projection 1025 define a second slot 1021, and the first body 1014 and the second body 1024 are arranged crosswise.
Since each of the first projection 1015 and the second projection 1025 is configured in a bent shape, each of the first projection 1015 and the second projection 1025 has a folded structure. This makes it possible to concentrate a plurality of radiation regions existing on the surface of the radiation element 10 (the horizontally polarized antenna element 101 and the vertically polarized antenna element 102), and to shorten the pitch of the respective radiation sources, so as to achieve better directivity of the pattern and higher gain. Specifically, the radiation elements 10 having the folded structure may not split the beam of the dual-polarized antenna 1, i.e., reduce the distance between the radiation sources and keep the electrical length of the dual-polarized antenna 1 unchanged, thereby implementing a beam with high frequency and low frequency nearly identical, so that the dual-polarized antenna 1 has identical beam coverage at high frequency and low frequency.
The first tab 1015 may be formed by stamping a portion of the first body 1014 or the first tab 1015 may be welded to the first body 1014.

Thereby, the first feeder cable 202 and the second feeder cable 302 can be more conveniently arranged, and the first feeder cable 202 and the second feeder cable 302 are prevented from influencing each other.

In summary, the feeding manner of the dual-polarized antenna 1 according to the embodiment of the present invention can also be divided as follows:
1. double balanced transmission line feeding: the feeding mode of the double balanced transmission lines refers to that the horizontal polarization antenna unit 101 and/or the vertical polarization antenna unit 102 have two feeding points for feeding, each feeding point is directly connected with the first ends of the two balanced transmission lines, and the second ends of the two balanced transmission lines are connected with other antenna components or radio frequency equipment. That is to say, the second end of the balanced transmission line can further complete the feeding unit by connecting transmission lines, balun structures, coaxial cables, etc. of different wires in sequence, and other newly added transmission lines, balun structures, coaxial cables, etc. of different wires can be regarded as a supplementary part of the feeding unit of the present invention, and any addition and modification made to the newly added antenna component by those skilled in the art should be regarded as a part of the feeding unit of the present invention.
2. Feeding a single balanced transmission line: the single balanced transmission line feeding mode means that the horizontally polarized antenna unit 101 and/or the vertically polarized antenna unit 102 have a feeding point for feeding, and the feeding point is directly connected to the first ends of the two balanced transmission lines, and the second ends of the two balanced transmission lines are connected to other antenna components or radio frequency devices, etc.
3. Unbalanced transmission line feeding: the unbalanced transmission line feeding method is to directly connect one or two feeding points of the horizontally polarized antenna unit 101 and/or the vertically polarized antenna unit 102 to feed by using an unbalanced transmission line material such as a coaxial cable.
It should be noted that the feeding method of horizontally polarized antenna element 101 may be the same as that of vertically polarized antenna element 102, and the feeding method of horizontally polarized antenna element 101 may be different from that of vertically polarized antenna element 102. Therefore, the dual-polarized antenna 1 according to the embodiment of the present invention has very rich feeding modes, and can meet the requirements of antenna performance and indexes.
Compared with the feeding unit of the existing dual-polarized antenna, the feeding units (the first feeding unit 20 and the second feeding unit 30) of the dual-polarized antenna 1 according to the embodiment of the present invention have the following differences and advantages:
1. because the present invention does not need to only adopt a robert balun structure, the present invention can adopt a balanced transmission line or an unbalanced transmission line to directly connect the horizontal polarization antenna unit 101 and the vertical polarization antenna unit 102 for feeding. Therefore, the structural design of the dual-polarized antenna 1 is optimized and reduced, the performance of the dual-polarized antenna 1 is improved, the cost of the dual-polarized antenna 1 is reduced, and a new feed unit design idea is provided for the dual-polarized antenna 1.
2. Horizontally polarized antenna element 101 and vertically polarized antenna element 102 have one or two feed points on them to feed them. Advantageously, the performance of the dual-polarized antenna 1 can be better improved by arranging two feeding points, and the requirements of each index of the dual-polarized antenna 1 are met.
Providing two feeding points for feeding on the horizontally polarized antenna element 101 and the vertically polarized antenna element 102 has the following advantages compared to providing one feeding point: (1) if the horizontally polarized antenna unit 101 and the vertically polarized antenna unit 102 are fed by using one feeding point, the horizontally polarized antenna unit 101 and the vertically polarized antenna unit 102 can only feed from above and below, respectively, resulting in an increase in the volume of the dual-polarized antenna 1, and the first feeding unit 20 and the second feeding unit 30 can be staggered above or below the antenna by using two feeding points, so that the volume of the dual-polarized antenna 1 can be reduced on the premise of ensuring the directional performance; (2) the feeding mode of the two feeding points can adjust the feeding positions, the design of the dual-polarized antenna 1 is optimized, the dual-polarized antenna 1 is conveniently adjusted to optimize the performance of the dual-polarized antenna 1, specifically, when the two feeding points are arranged, the two feeding points are only symmetrical about the center, so that the positions of the two feeding points can be adjusted, and when one feeding point is arranged, the feeding can be only carried out in the middle of the horizontal polarized antenna unit 101 and the vertical polarized antenna unit 102, so that the better performance can be realized; (3) the performance deterioration caused under the condition of one feeding point is avoided, and the influence of adjacent transmission lines on each other when one feeding point is arranged under two feeding points can be avoided, so that the antenna isolation is low and the cross polarization is deteriorated.
3. The first feeding unit 20 and the second feeding unit 30 may use a balanced transmission line or an unbalanced transmission line as a feeding wire, and there are many design schemes. The unbalanced transmission line and the balanced transmission line are selected to have the following differences: (1) the antenna has the best performance, and must have "balanced current", what is transmitted in the balanced transmission line is balanced current, can solve the unbalanced phenomenon of feed well, make the directional diagram of the dual polarized antenna 1 realize better symmetry.
