Embodiment Construction

[0017] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a base station antenna and a dual-polarized antenna oscillator thereof. Because each oscillator unit is provided with a main polarized radiation arm and an auxiliary radiationarm, current extends and flows along the main polarized radiation arm and the auxiliary radiation arm, thereby prolonging a current path and standardizing the current path. Furthermore, because the main polarized radiation arm extends along the polarization direction, most of the current paths on radiation sheets are consistent with the polarization direction of an oscillator unit. The area fraction of the current in the same direction as the polarization direction determines the intensity of the excitation field. Because the integral area of the current in the dual-polarization direction ofthe antenna oscillator is obviously increased, the gain is improved. Moreover, due to the increase of the current paths in the dual-polarization direction, the current paths perpendicular to the polarization direction are relatively reduced, so that the excited cross polarization current is very small, and the isolation degree is effectively improved. Therefore, the radiation indexes of the base station antenna and the dual-polarized antenna oscillator thereof are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a base station antenna and a dual-polarized antenna dipole. Background technique [0002] With the advancement of 5G network plans around the world, the research and development of base station antennas in new frequency bands is being carried out on a large scale. Due to the increase in operating frequency and the increasing popularity of base station antenna miniaturization, the miniaturization of antenna elements and the reduction of the spacing between elements have become necessary means to achieve their goals. However, the ensuing problems also appeared at the same time. For example, the reduction of antenna dipoles will lead to a decrease in gain; and the reduction of the spacing between dipoles will cause the deterioration of the isolation and coupling between dipoles. Therefore, the radiation index of the base station antenna will be poor. Contents of t...
