Description

Antenna structure assembly

This application relates to the field of communications, in particular to an antenna structure assembly.

Nowadays, electronic products have an increasing demand for wireless communication functions. There may be multiple antennas in a product, but signal interference is likely to occur between the antennas and the antennas. Therefore, the isolation of the antenna has become the key to today's wireless communication. In the past, there are several ways to improve antenna isolation. The simplest way is to directly increase the distance between adjacent antennas. Antenna isolation can be improved as the adjacent distance increases. However, within the limited size of the product, it is usually not possible to provide ample distance for the antenna, so there are practical application restrictions.

Secondly, some documents propose to design two adjacent antennas with different polarizations to reduce the electromagnetic field interference between each other. However, due to the different polarization of the two adjacent antennas, it is easy to cause the side effect of the overall radiation efficiency decline. Furthermore, a quarter-wavelength isolator (Isolator) can be added between the two antennas, but in the same size, although the addition of the isolator can improve the isolation of adjacent antennas, the original characteristics of the antenna will be affected. This will result in the degradation of the communication quality of the product in the long-distance transmission and reception.

FIG. 15 is a spectrum diagram measured in the embodiment of FIG. 1, and the width d1 of the first gap G1 is designed to be 5 mm. Compared with FIG. 14, there is no obvious change in the lower curve. The addition of the conductive shielding wall 30 and the connecting portion 40 indicates that the impedance and frequency response of the first antenna 10 and the second antenna 20 have no obvious influence. However, the downward movement of the upper curve indicates that the signal strength received by the second antenna 20 from the first antenna 10 is greatly reduced, that is, the isolation between the first antenna 10 and the second antenna 20 is greatly improved .

In conventional technology, it is generally believed that the metal shield will reduce electromagnetic radiation and increase the electrostatic discharge discharge path, which will reduce the antenna function, which will seriously affect the user's experience in wireless communication applications, and the closer the distance between the metal shield and the antenna, the more serious it will be. Therefore, the antenna will not be designed adjacent to the housing or metal wall. However, in this case, the conductive shielding wall 30, the connecting portion 40, and the second gap G2 between the conductive shielding wall 30 and the ground plate 100 can overcome the conventional technical bias.
