Beam-Steering Antenna Brings Mobile Communications Above 5G

Real Estate Business Review | Thursday, January 20, 2022

The experimental outcome, presented at the 3rd International Union of Radio Science Atlantic/Asia-Pacific Radio Science Meeting, shows that the device can give continuous 'wide-angle' beam steering, enabling it to follow a moving mobile phone user.

FREMONT, CA: A group of proficients has revealed a new beam-steering antenna that improves data transmission efficiency for 'beyond 5G' - and reveals a spectrum of frequencies for mobile communications that are now inaccessible to current technology. This device is capable of offering continuous beam steering, which makes it possible to track a mobile phone user similarly that a satellite dish tracks a moving object, but at considerably faster speeds, based on the experimental outcomes presented at the 3rd International Union of Radio Science Atlantic/Asia-Pacific Radio Science Meeting.

The beam-steering antenna was created by Dr. James Churm, Dr. Muhammad Rabbani, and Professor Alexandros Feresidis, Head of the Metamaterials Engineering Laboratory, to settle the efficiency issues of fixed base station antennas at higher frequencies that impede them from being utilized for long-distance transmission.

The technology, around the size of an iPhone, is based on a metamaterial, a metal sheet with a grid of micrometer-sized pores. An actuator manages the height of a cavity within the metamaterial, delivering micrometer movements. The antenna controls the diversion of a radio wave beam according to its position, concentrating the beam into a highly guided signal and redirecting that energy as desired while growing transmission efficiency.

Including prototypes that will work with higher frequencies, the team is now working on applications extending beyond 5G mobile communications. A researcher at the University of Birmingham noticed that their models show how the beam steering technology might be capable of 94% efficiency at 300 GHz, even though it was built for 5G use. Moreover, he also noted that the technology could be adapted for use in vehicle-to-vehicle, vehicle-to-infrastructure, vehicular radar, and satellite communications, allowing it for next-generation usage in automotive, radar, space and defense applications.

At frequencies ranging the millimeter wave spectrum, particularly those identified for 5G (mmWave) and 6G, where high efficiency is presently only possible with sluggish, mechanically steered antenna technologies, the technology has shown vast advancements in data transmission efficiency.

The beam-steering antenna's Prototypes at 26 GHz have shown remarkable data transmission efficiency for 5G mmWave applications. The gadget is backward compatible with mobile communication networks' current 5G requirements. Also, in place of employing the complex and inefficient feeding networks essential for regularly deployed antenna systems, the new approach uses a low-complexity system that improves performance and is easy to build.

Dr. Churm observed that the simplicity of the design and the least cost of the elements are useful for early adoption by the industry. In addition, the compact electronics layout makes it straightforward to deploy where space is limited. The team opines that the beam-steering antenna is suitable for a wide range of 5G and 6G applications and the satellite and Internet of Things.

The University of Birmingham Enterprise has listed a patent for its next-generation beam-steering antenna technology and is looking for industry associates for cooperation, product development, and licensing.
