Pioneering research at Loughborough University could reduce mobile phone emissions into the body by up to 85%

12.06.2002


Loughborough University’s Centre for Mobile Communications Research (CMCR) has made some major breakthroughs in its antenna technology that could enable safer communication for all.

Using their work associated with GPS (Global Positioning System) technology, researchers have managed to reduce emissions into the body by as much as 85%. The CMCR achieved its breakthrough in antenna designs through innovative laser technology and super computing modelling techniques. This puts the University in an excellent position to be the leaders in low SAR (Specific Absorption Rate) solution providers in the UK for the Telecom industry. SAR is the parameter that measures the amount of radiation from mobile phone handsets absorbed by human tissue.

The Centre’s vital research to develop the definite low SAR mobile phone antenna has been recognised with grants from the Engineering and Physical Sciences Research Council, and it has already gained over £1 million in contracts covering many aspects of mobile communications such as GSM, 3G and BluetoothTM.



Professor Yiannis Vardaxoglou, head of the CMCR, commented, “The issue of mobile phone health is escalating rapidly and mobile handsets are now required to clearly state their SAR rating. Therefore it’s not surprising that a number of interested parties are examining ways of reducing SAR levels. For this reason we have made major investments in facilities such as super computers and a Dosimetric Assessment System which enables the radiation absorbed by a ‘phantom head’ to be accurately measured.”

One company which is outsourcing research work to the CMCR is Wellingborough-based miniature antenna manufacturer Sarantel as the company’s CEO, Barrie Foley, confirmed, “The CMCR at Loughborough University has some of the best super computer Radio Frequency modelling facilities in Europe. Design evaluations, which previously took many weeks, can now be completed in just a few days and so it makes a lot of sense for us to capitalise on their outstanding experience and facilities. This technology is real and can be delivered to the market, unlike many claims by various organisations in the past.”

Sarantel and Loughborough have previously worked together on antenna designs for GPS handsets based on the company’s PowerHelix™ technology. These antennas use helical copper tracks etched onto a ceramic puck and are finding wide acceptance with GPS handset and wireless location device manufacturers. They offer many technical benefits such as a low ‘Near Field’ which enables weak GPS satellite signals to be captured even when the equipment is in close proximity to buildings or the body of the user.

A possible by-product of the work done with Sarantel is the reduction of mobile phone antenna Near Fields in order to reduce the SAR rating of handsets. Professor Vardaxoglou explained, “If the near field could be reduced to a few millimetres with a high level of predictability, then a low SAR antenna could be a real possibility.”A selection of quality, high resolution photographs of mobile phone antenna production at Sarantel exploiting CMCR research are available to down load from the Gallery at http://www.lboro.ac.uk/departments/el/research/cmcr

Im Focus: First quantum photonic circuit with electrically driven light source

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.

Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
