ANTENNAS FOR 5G COMMUNICATION
Key technologies in 5G:
The Massive MIMO and millimeter wave technologies are considered to be the key technologies for 5G wireless communication. So, the MIMO, lower microwave band or millimeter band is used, at which the antenna is integrated with RF transceivers. By this, 5G Antennas has specific traditional characteristics.
Challenges for 5G Antennas :
As from virtual to reality and everything seems to in automation from vehicles to industries, 5G is considered as the “heart of the future communications”.
So, this fifth generation requires higher frequencies, more data ranges with wide bandwidth, which are all the significant challenges for antenna designers. Low-profile efficient and interference free communication is needed, but requirements to the presence of human user further complicate the antenna and its propagation aspects too.
How do Antennas work with 5G? :
Smart Antennas use a technique called “beamforming” to improve 5G capability. It is technique in which RF signals are focused in a narrow path exactly rather than emanating them wider. Because there is greater probability in optimal bandwidth and signal quality for more directed beam of RF energy. Optimal signals will change frequently during 5G data or voice connection, that is best signal will change from antenna to antenna in an antenna array.
• Millimeter wave RF propagation
• Increased coverage
• Enables fast communication at RAN (Radio Access Network)
• Ultra-reliability and ultra-low latency
Antenna supported 5G applications :
* Mission Critical Communications
(provide path for improved voice and data, enable machine-oriented communication).
* Industrial Automation and Robotics
(autonomous robotics, cloud robotics, allowed for next phase of industrial and Robotics revolution).
* Self-driving vehicles, Drones and Unmanned Aerial Vehicles (UAV)
(promoting V2X – vehicle-to-everything technology, Ariel drone without human intervention).
