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. Each oscillator unit is provided with a main polarization radiation arm and an auxiliary radiation arm,a current extends and flows along the main polarization radiation arm and the auxiliary radiation arm, and the current path is extended and standardized. Further, the main polarization radiation armextends along the polarization direction, so that most of the current path on radiation fins are consistent with the polarization direction of the oscillator unit. The integral area of the current inthe same direction with the polarization direction decides the magnitude of the excitation field intensity. The integral area of the current in the double polarization direction of the antenna oscillator is increased substantially, so that the gain is improved. The current path in the double polarization direction is increased, the current path in the direction vertical to the polarization direction is reduced relatively, and thus, the excited cross polarization current is extremely low, and further the isolation degree is improved effectively. The radiation index of the base station antenna and double polarized antenna oscillator thereof are improved substantially.

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 improvement of operating frequency and the increasing popularity of the miniaturization of base station antennas, 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. Co...
