Embodiment Construction

[0042] 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.

[0043] 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 present invention relates to a MIMO antenna array and a reflective substrate thereof. A high-frequency radiation unit array or isolation plate located in an isolation region can isolate two hybridradiation unit arrays located in a first installation area and a second installation area to improve isolation. Further, by adjusting the distance between an adjustment plate and the high-frequency radiation unit array (or isolation plate), the combination boundary of the adjustment plate and the high-frequency radiation unit array (or isolation plate) cancels out the reflection boundary asymmetry caused by the reflective substrate, thereby improving the boundary symmetry of the hybrid radiation unit arrays and further improving the directional diagram of the MIMO antenna array. In addition,the adjustment plate is placed under a low-frequency radiation arm in a high-low frequency nested radiation unit, and can improve the boundary symmetry of the low-frequency radiation unit in the high-low frequency nested radiation unit, thereby improving a low-frequency standing wave and the isolation. Therefore, the directional diagram indicators and the circuit indicator of the MIMO antenna array are improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a MIMO antenna array and an antenna reflection plate thereof. Background technique [0002] With the development of antenna technology, multi-frequency and miniaturized antennas have become the development trend of base station antennas. The high and low frequency nesting scheme is the most mainstream method to realize multi-frequency and miniaturized antennas. MIMO (Multiple-Input Multiple-Output) technology is a multi-antenna technology, that is, the receiving end and the transmitting end of the wireless communication system are equipped with multiple antennas, so that the signal is transmitted and received through multiple antennas at the transmitting end and the receiving end. Thereby improving the communication quality. In the current mobile communication environment in which 2G, 3G and 4G networks coexist, in order to save site and improve spectrum utilizat...
