Embodiment 1

[0030] Example 1, the number of die casting array antenna 2 is disposed, and there are 4, and the antenna array of 2 * 2 is configured. In other embodiments, the structure and principle of the die cast array antenna may also be employed in the present embodiment. like Figure 4-5 As shown, the total size of the die-casting antenna vibrator 2 is 53.14 mm * 53.14 mm * 47.06 mm (length * width * height), including the feed sheet 21 of the metal material, Branette 22, the radiation arm 23, and the plastic gasket 25. The number of Valen 22 is two, and is fixed to the reflective bottom plate 1 through the circular hole 11 to support antenna and impedance transformation. The plastic gasket 25 is placed between the Baron 22 and the reflection bottom plate 1, and the current propagation path is cut off.

[0031] The radiation arm 23 is provided with two groups, and the two sets of radiation arms are orthogonal, and each group is the same as the two dimensional shapes (length * width of 25.1...

Abstract

The invention discloses a high-isolation antenna for 5G mobile communication in the field of mobile communication, which comprises an angle-adjustable reflection bottom plate. A metal isolation strip and a plurality of die-casting antenna arrays arranged in an array are fixed on the reflection bottom plate, and the die-casting antenna arrays are symmetrically arranged in the front-back direction relative to the metal isolation strip. The metal isolation strip and the top of the die-casting antenna array are located at the same height. A power divider is further fixed to the bottom of the reflection bottom plate and connected with the die-casting antenna arrays through coaxial transmission lines. The mutual coupling effect between the antenna units is reduced, and the risk of signal crosstalk is reduced.

Description

Technical field [0001] The present invention relates to the field of mobile communications, in particular a high isolation antenna for 5G mobile communication. Background technique [0002] With the explosive growth of mobile broadband services, the 5G communication system has launched a business deployment. Outdoor macro station, indoor small station, microcontroller, etc., form a stereo coverage network, which increases network density. In order to meet the gradually increased network optimization needs, operators must seek an antenna program that is easy to operate, high efficiency, low cost and flexibility. Among them, the antenna is a method for realizing the commonality of network optimization. However, the mechanical lowerling will lead to directional diagram distortion, increase inter-cell interference, affect user experience, and difficult to meet network operational requirements of high efficiency and large data. For the design of the base station antenna, the form of a...
