The parabolic directional 4x4 MIMO antenna is a high-performance wireless communication antenna. The following will introduce its principles, characteristics, applications, etc.:
Working principle
Reflection focusing principle: The signal from the transmitting source is reflected and focused in one direction through the parabola to form a high-gain directional beam, so that the signal energy is concentrated in a specific direction, and the signal strength and transmission distance are enhanced.
MIMO technology principle: Equipped with 4 transmitting antennas and 4 receiving antennas, using spatial multiplexing technology, multiple independent data streams can be transmitted simultaneously in the same frequency band, and diversity technology can be used to improve the reliability of signal transmission.
Structural characteristics
Parabolic structure: It is usually composed of a parabolic reflector and a feed source at the focus. The shape and size of the parabola will affect the performance of the antenna, such as gain, beam width, etc.
Multi-antenna layout: At the focus or nearby position of the parabola, 4 transmitting antennas and 4 receiving antennas are reasonably arranged to achieve 4x4 MIMO function.
Performance advantages
High gain: It can concentrate the signal energy in a specific direction and obtain a very high gain, which can generally reach more than 10dBi, which can effectively enhance the signal strength and extend the transmission distance.
Low interference: It has strong directivity and can reduce interference signals from other directions, improve signal quality and anti-interference ability.
High data transmission rate: Combined with the spatial multiplexing capability of MIMO technology, it can significantly increase the data transmission rate, network capacity and spectrum utilization without increasing bandwidth.
Application scenarios
Long-distance communication: It is often used for long-distance point-to-point communication, such as in remote areas such as mountains, deserts, and seas, to achieve long-distance data transmission between base stations or between base stations and terminals.
Special industrial environment: In large industrial plants, mines and other environments, it is used to connect key communication equipment in different areas to ensure reliable and high-speed transmission of data in complex industrial environments.
Military field: It can be used for military communications, radar systems, etc., to meet the requirements of military applications for high gain, low interference and high reliability communications.
