LONDON Fractal antenna technology pioneer Fractus (Barcleona, Spain), has launched an ultrawideband antenna for the short-range wireless market. Some of the leading UWB chip companies have already evaluated the fractal antenna and plan to offer it as an option in their devices.
Dubbed the UWB Media+ Chip Antenna , the device meets the requirements of reference designers, OEMs and ODMs utilizing the 3.1-5GHz spectrum as specified by the WiMedia Alliance, which includes members Intel, Texas Instruments, Microsoft, Philips Electronics, Nokia, Staccato Communications and others for UWB development.
Staccato is already known to have tested the device and is offering it as an option in its all-CMOS UWB chip.
Measuring just 10x10x0.8mm, the UWB antenna combines an omni-directional radiation pattern and high efficiency level to deliver the largest bandwidth possible.
Fractus says the size provides flexibility to device designers and easily integrates into space-limited PCBs in digital cameras, home-cinema equipment, PC peripherals, PDAs, mobile phones, and compact-flash cards.
"UWB and the extensive range of devices that are about to become wirelessly enabled represents a huge opportunity for device manufacturers" said Tim Hillison, Fractus' short-range wireless division director. "Manufacturers who choose Fractus' fractal technology gain a clear competitive advantage in terms of cost, performance and device size."
Fractus pioneered the use of fractals in antenna design and development, and is now using its proprietary technology to integrate miniature antennas into semiconductor packages (Antenna-in-Package).
The products are already used in mobile phones, wireless consumer electronics using Bluetooth, WLAN and base stations.
The first patent for fractal design applied to mobile telecommunications antennas was filed by Fractus Chief Technology Officer Carles Puente in 1995. The company now holds 36 patents for fractal technology, which relies on a geometric pattern repeated at ever-smaller scales so that each is a smaller copy of the whole.
Fractal shapes are often self-similar (segments look like each other and like the whole object) and independent of scale.
