The dual-polarized director 110 comprises a first director and a second director which are orthogonally arranged, and the first director and the second director comprise a plurality of metal pieces which are arranged on the antenna axial rod 140, wherein the metal pieces can be metal rods or metal strips. The metal member is perpendicular to the antenna axial rod 140, and the vertical leg coincides with the midpoint of the metal member, so that the two ends of the metal member are symmetrically disposed on the antenna axial rod 140. Meanwhile, the length relationship among the metal pieces is as follows: the lengths of the metal parts are different, and the length of each metal part is shorter than that of the adjacent metal part close to the dual-polarized active oscillator, namely the lengths of the metal parts are sequentially shortened along the direction from the end B to the end A; or the metal pieces can be divided into a plurality of groups along the direction from the end B to the end A, the length of the plurality of metal pieces in each group is the same, but the length of each group of metal pieces is shorter than that of the adjacent group of metal pieces close to the end B. Meanwhile, when the first director and the second director are orthogonally combined into the dual-polarized director, the metal pieces with the same length are also kept orthogonal and in the same plane, that is, the metal pieces with the same length form a cross shape as shown in the figure and are arranged on the antenna axial rod 140.

The length of the piece of metal of dual-polarized reflector 130 is longer than the length of any piece of metal of dual-polarized director 110.

As shown in fig. 9, the dual-polarized active element 120 includes two identical single-polarized active elements that are orthogonally disposed, that is, a first active element and a second active element, and each of the two same single-polarized active elements is composed of two L-shaped metal elements that are symmetrically disposed on two sides of the antenna axial rod 140, one of the arms of the L-shaped metal element is a connecting arm 121 attached to the antenna axial rod 140, and a port 122 on the connecting arm 121 is connected to a corresponding metal element of the dual-polarized reflector 130, that is, one L-shaped metal element of the first active element is connected to a metal element on one side of the first reflector, the other L-shaped metal element of the first active element is connected to a metal element on the other side of the first reflector, and the description of the second active element is omitted here. The length of the connecting arm 121 can be adjusted according to actual requirements, such as the wavelength of the signal transmitted and received by the antenna.

Specifically, the sum of the lengths of the two functional arms of the active element, which are disposed on the two sides of the antenna axial rod 140, is greater than the length of any one metal piece of the dual-polarized director 110, and is less than the length of the metal piece of the dual-polarized reflector 130. The angle between the connecting arm 121 and the functional arm 123 of the L-shaped metal member can be adjusted according to the actual signal transceiving requirement, and in one embodiment, the angle between the connecting arm 121 and the functional arm 123 of the L-shaped metal member is 90 °.

Referring to fig. 10, the relationship between dual-polarized director 110, dual-polarized active element 120 and dual-polarized reflector 130 further comprises: the first active oscillator, the first reflector and the first director are positioned in the same plane, the second active oscillator, the second reflector and the second director are positioned in the same plane, and the view of the whole antenna from the A end to the B end is approximately in a cross shape.

The F-B cover layer 400 may be a rectangular patch, a circular patch, or a cross-shaped patch, and functions to form a reflective surface 1. Specifically, taking the reinforced dual-polarized yagi antenna 12 as an example, the first end of the antenna axial rod 140 is used as a ground proximal end, the second end of the antenna axial rod 140 is used as a ground distal end, and then the antenna floor (for example, the ground may be used as an antenna floor) is the reflection surface 2, the F-B covering layer 400 forms the reflecting surface 1, an F-B resonant cavity (i.e., a fabry-perot resonant cavity) is formed between the reflecting surface 1 and the reflecting surface 2, other components of the whole enhanced dual-polarized yagi antenna are located between the reflecting surface 1 and the reflecting surface 2 (i.e., located in the fabry-perot resonant cavity), and electromagnetic waves radiated by antenna elements (e.g., the dual-polarized active elements 120) in the enhanced dual-polarized yagi antenna 12 are superposed in phase in the F-B resonant cavity, so that the radiation gain of the enhanced dual-polarized yagi antenna is improved.

The type of the F-B cover layer 400 is not exclusive, for example, the F-B cover layer 400 may employ a graded dielectric constant cover layer, and the use of different dielectric constants at different positions of the cover layer can make the phase distribution curve more uniform, thereby improving the quality of the electromagnetic wave radiated by the enhanced dual-polarized yagi antenna. The F-B cover layer 400 is not only disposed, but may be fixedly disposed at the second end of the antenna axial rod 140 during shipment or installation to keep the position fixed, so that the F-B cover layer 400 and the antenna axial rod 140 are structurally integrated, thereby avoiding interference factors caused during installation and improving the working performance. The antenna can also be arranged at the second end of the antenna axial rod 140 through a connecting piece, the type of the connecting piece is not unique, the connecting piece can be a foam connecting piece or a connecting column, and the like, furthermore, the F-B covering layer 400 can also be detachably fixed at the second end of the antenna axial rod 140 through the connecting piece, the F-B covering layer 400 can be installed as required, the F-B covering layer 400 does not need to be detached, the use is convenient, and when the F-B covering layer 400 is damaged and cannot be used, the F-B covering layer 400 can only be replaced, the integral replacement of the reinforced dual-polarized yagi antenna 12 is avoided, and.

In one embodiment, referring to fig. 1, the number of F-B overlays 400 is two or more (only one F-B overlay 400 is shown in fig. 1), each F-B overlay 400 being stacked and spaced apart from dual-polarized director 110 and away from the first end of antenna axial rod 140. Taking the first end of the antenna axial rod 140 as the ground-near end and the second end of the antenna axial rod 140 as the far-ground end as an example, stacking the plurality of F-B cover layers 150 at the second end of the antenna axial rod 140 may enable the electromagnetic waves radiated by the dual-polarized active oscillator 120 to be more in-phase superposed quantity when the electromagnetic waves are propagated in a fabry-perot resonant cavity formed by the plurality of F-B cover layers 150 and a plane (e.g., the ground) where the first end of the antenna axial rod 140 is located, thereby further improving the radiation gain of the enhanced dual-polarized yagi antenna.

In one embodiment, the patch has a cross-shaped slot on a side thereof adjacent to the second end of the antenna axial rod 140. The cross-shaped groove plays a role in meander, so that equivalent inductance is increased, and resonant frequency is obviously reduced, so that the size of the F-B covering layer 400 can be reduced on the premise of ensuring working performance, and stronger radiation generated by the cross-shaped groove is equivalent to increase larger loss resistance, thereby greatly improving bandwidth.
