Specifically, the radiation sheet assembly 30 further includes a first layer of radiation sheets 31 and a second layer of radiation sheets 32, and the second layer of radiation sheets 32 is located between the first layer of radiation sheets 31 and the reflection plate 13. The second layer of radiating fins 32 is a main radiating fin, and the radiation field of the antenna element mainly exists between the second layer of radiating fins 32 and the wall 10, which mainly determines the directional diagram radiation characteristic working frequency band of the antenna element. The first layer of radiating fins 31 are used for expanding the working frequency band of the antenna element and improving the beam convergence of the antenna directional pattern.
The antenna element unit further includes a supporting member (not shown) having one end connected to the radiation fin assembly 30 and the other end connected to the wall 10 or the reflection plate 13, for fixing the radiation fin assembly 30.

Preferably, the number of the second grooves 130 and the first grooves 22 is two or more, respectively, and the first grooves 22 and the second grooves 130 are provided rotationally symmetrically.

Referring to fig. 4, which shows a pattern diagram when the first groove 22 and the second groove 130 are simultaneously formed on the reflection plate 13, the symmetry of cross polarization thereof is significantly improved. In fig. 3 and 4, the abscissa is the horizontal plane angle of the antenna pattern, and the ordinate is the level value of the pattern at each angle, and a higher pattern indicates better cross polarization performance. By forming the second slots 130 in the reflector 13 and in the periphery of the first slot 22 in a rotationally symmetric manner, signals generated by the feed conductor 21 can be more uniformly propagated to the second cavity 142, so that the cross polarization of the antenna element unit can be effectively improved, and the improvement of the cross polarization of the element pattern is of great significance to the formation.

In the preferred embodiment, by disposing the dielectric plate 16 between the feeding conductor 21 and the bottom plate 11, the distance between the feeding conductor 21 and the bottom plate 11 is increased, which is equivalent to the effect that the radiation field is coupled into the radiation plate assembly 30 through the LC coupling structure formed by the resonant structure 20.
The distance between the reflective plate 13 and the bottom plate 11 can be effectively reduced by disposing the dielectric sheet 16 in the first chamber 141, reducing the thickness of the first chamber 141.
