Flat Panel Directional MIMO 4x4 Antenna

　　The flat directional MIMO 4x4 antenna is an advanced wireless communication antenna. The following will introduce its principles, advantages, applications, etc.:

　　Working principle

　　MIMO technology foundation: through 4 transmitting antennas and 4 receiving antennas, multiple independent data streams are transmitted simultaneously in the same frequency band, and the communication capacity and efficiency are improved by using the spatial dimension.

　　Directional radiation principle: through specially designed antenna arrays and feeding networks, the signal is concentrated in a specific direction for radiation, so that the signal strength and transmission distance in that direction are significantly improved.

　　Features

　　High gain: It can concentrate the signal in a specific direction, enhance the signal strength, and improve the antenna gain. For example, in the 600-2700MHz frequency band, the gain of some products can reach 15dBi.

　　Spatial multiplexing and diversity gain: Support spatial multiplexing technology to improve the data transmission rate, and use diversity technology to improve the reliability of the received signal.

　　Strong anti-interference ability: The directional radiation characteristics make the signal more concentrated, reduce the influence of interference signals in other directions, and MIMO technology can further suppress interference through signal processing algorithms.

　　Compact and lightweight: Flat-plate structure design, small size, light weight, easy to install and integrate, suitable for a variety of scenarios.

　　Application fields

　　Mobile communication network: In 4G and 5G base stations, it can accurately cover user-concentrated areas, improve spectrum efficiency, and meet the high-speed data service needs of a large number of users.

　　Wireless LAN: Enterprise-level wireless access points use this antenna, which can provide directional coverage according to the layout of the office area, reduce signal interference, and provide high-quality network connection for employee devices.

　　Internet of Things: In smart factories, it helps various devices communicate with gateways to achieve real-time monitoring and automatic control of production processes; in the field of smart transportation, it supports communication between Internet of Vehicles devices and roadside infrastructure or other vehicles.

　　Typical products

　　WMM 4G(G)-6-60: Four independent broadband component components can be integrated into a single housing, with a peak gain of 6dBi in the 617-960MHz frequency band and a peak gain of 9dBi in the 1710-6000MHz frequency band. The protection level is IP66 and is suitable for outdoor environments.

　　AL-TX001: 5G antenna high gain MIMO 4x4 plate antenna, frequency range 600-4000MHz, outdoor waterproof function, suitable for a variety of communication scenarios.

　　Installation and maintenance

　　Installation points: During installation, the antenna direction and angle must be adjusted according to the target coverage area to ensure that the signal can be accurately radiated to the required area; at the same time, the appropriate spacing between antennas must be maintained to avoid signal interference.

　　Maintenance matters: Regularly check the appearance of the antenna for damage, aging, etc., clean the dust and debris on the surface of the antenna; check whether the connecting parts of the antenna are loose to ensure stable signal transmission.
