iPhone-sized beam navigator to take mobile communications beyond 5G: Study


In a step that could help achieve better network connectivity in the near future, scientists have developed a beam-directed antenna that enhances data transmission beyond the 5G standard. This will allow access to a wide range of frequencies for mobile communications that were previously out of reach. With the size of an iPhone, the beam-guided antenna has been developed as a better alternative to the fixed base station antennas in use today. Fixed antennas are not efficient at higher frequencies which have limited their use for long distance transmission.

New device capable of tracking a mobile Phone is just one way satellite track a moving subject, but at a much faster rate. Develop By researchers from the University of Birmingham, the device provides a continuous wide-angle beam and has been found to be effective in improving the efficiency of data transmission at different frequencies across the millimeter wave spectrum. These include frequencies such as for 5G (mmWave) and 6G where high efficiency is achieved using mechanical navigation antenna solutions.

The test results of the device were recently presented at the 3rd International Atlantic/Asia-Pacific Alliance Radio Science Conference.

The new technology has been made compatible with the existing 5G specifications being used by mobile communication networks. In addition, the device does not require the inefficient and complex power supply networks used by conventional antenna systems. It is based on a low complexity system that increases performance and is also easy to fabricate.

The scientists developed the device using a metamaterial, created from a sheet of metal containing evenly spaced holes micrometers in diameter. It has been fitted with an actuator that controls the height of the cavity in the metamaterial and allows the antenna to focus radio waves into high indication signals. This leads to a significant increase in transmission efficiency.

Highlighting the potential of the device, Dr. James Churm, one of the lead researchers, speak“While we have developed the technology for use in 5G, our current models show that our beam-guided technology can be 94% efficient at 300 GHz.”

He added that the device has many uses such as in vehicle radar, satellite communication, space and defense and automotive applications, among others.
