Technical Field

Background

In recent years, the fifth generation mobile communication system 5G has become a hot spot of discussion in the communication industry and academia. There are two major driving forces for the development of 5G. On one hand, the fourth generation mobile communication system 4G represented by the long term evolution technology is completely commercialized, and the discussion of the next generation technology is scheduled; on the other hand, the demand for mobile data is increasing explosively, the existing mobile communication system is difficult to meet the future demand, and the development of a new generation of 5G system is urgently needed. The development of 5G also comes from the increasing demand for mobile data. With the gradual maturity and popularization of 5G, people begin to enjoy the service experience of high speed, low time delay and high reliability brought by the 5G technology, and the 5G mobile phone starts to enter the visual field of users as an important role in the mobile internet wave. The high-speed requirements of people in games and video and audio scenes require that more antennas with more frequency bands than those in the 4G era are plugged in the limited space of a mobile phone.

MIMO antennas represent multiple input multiple output. MIMO techniques can be broadly divided into two categories: transmit/receive diversity and spatial multiplexing. MIMO antennas are sometimes referred to as spatial diversity because they use multiple spatial channels to transmit and receive data, and the capacity of the channel can be increased using MIMO techniques. However, the MIMO antenna has a plurality of transmitting terminals, which easily generates large heat, so that the overall temperature of the device is too high, and the lifetime of the device is short. Therefore, a communication device with better heat dissipation for 5G technology MIMO antenna is needed. In this regard, CN 209804869U provides a 5G-oriented massive MIMO antenna radiator, but the radiator adopts a water tank and a heat sink to cooperate to achieve heat dissipation, so that the structure is complex.

Detailed Description

The MIMO matrix communication antenna 2 is also called a Multiple Input Multiple Output (MIMO), and in order to greatly increase channel capacity, a plurality of antennas are used at both the transmitting end and the receiving end, and an antenna system of a plurality of channels is formed between transmission and reception.

Mimo is a rather complex antenna diversity technique. Multipath effects affect signal quality, and thus conventional antenna systems have a strong interest in eliminating multipath effects. In contrast, the MIMO system utilizes multipath effects to improve communication quality. In the MIMO system, both the transmitter and the receiver use a plurality of antennas that can operate simultaneously to perform communication. MIMO systems typically employ complex signal processing techniques to significantly enhance reliability, transmission range, and throughput. The transmitter uses these techniques to simultaneously transmit multiple rf signals, from which the receiver recovers the data.

The MIMO matrix communication antenna 2 generates a large amount of heat during operation, and the heat is conducted to the protective case through the first heat conductive material layer 31 in contact therewith to be discharged. The damage of the MIMO matrix communication antenna 2 caused by high heat is avoided, and the service life of the communication device is prolonged. The protective housing 1 in this embodiment can be made of plastic because the metal has strong signal interference and the heat dissipation effect is good, so that the heat conducted to the protective housing 1 can be dissipated as soon as possible.
