Fractal antenna technology company Fractus has been granted key patents for Space-filling antenna technology. This new approach results in smaller antennas, enabling smaller handsets or existing models that have the capacity to accommodate new in-demand multimedia features. In addition the technology allows small antennas to operate on lower frequency cellular standards that have formerly required a bulky internal antenna or even an external design.
The Space-filling Antenna patents have been granted in the US and in other strategic markets. The technology is based on fractal geometry, meaning that antennas can occupy a small space in the most efficient way possible. This results in far smaller antennas – and therefore devices – or given a fixed size specification, an antenna that can operate on lower frequencies than existing designs.
Fractus says the technology will create extra physical space for a variety of other technologies increasingly entering the mobile handset, such as digital cameras and MP3 players as well as the variety of technologies required for more powerful Smartphones.
Additionally, there is currently significant operator interest in lower frequencies which enable far larger cell sizes, thus reducing the cost of network roll-out, as well as improved in-building penetration. GSM, CDMA and FLASH-OFDM are being deployed at 450MHz as well as numerous Mobile TV standards in the sub-600MHz range, but these lower frequencies typically require larger antennas and therefore larger end-user devices. Fractuss technology allows existing terminals which operate at higher frequencies to be re-purposed for these low-frequency standards.
We live in an exciting age where new cellular standards are enabling compelling new features and services says Fractus CTOO Dr. Carles Puente,. However, accommodating these standards into a small attractive device is no mean feat – this is where were beginning to make a name for ourselves.”   
Fractuss patent portfolio encompasses 49 inventions, including 140 national patent and patent applications world wide. 10% of Fractus employees hold a PhD and 60 per cent are telecoms engineers. 
Fractus has published 50 IEEE (Institute of Electrical and Electronics Engineers) papers and spoken at dozens of international conferences on the latest advances in mobile device and base station antenna technologies. Its customers include Samsung, Sagem, CSR, Philips Semiconductors and Siemens.
