Fractus antenna enables FM radio in new portable devices
10/11/2007
Fractus has announced its first standard antenna for the FM frequency. The FracFM antenna's compact dimensions (32 X 11 X 1.6mm - about one third the area of a normal postage stamp), make it a suitable high-performance solution for portable devices such as ultra-mobile PCs (UMPCs), gaming devices, personal digital assistants (PDAs), private mobile radio (PMR) and laptops.
FracFM requires no active amplification or tuning, meaning it covers the entire FM frequency range (78-108 MHz), without the need for extra components, providing not only high performance, but also cost savings and a reduced bill-of-materials. The antenna has been designed and tested with the user and the different propagation environments in mind to ensure consistent performance.
A traditional antenna design approach requires an antenna that is longer than most portable devices. This means the antenna has been integrated into the headphone cable, rendering the device useless without it and unsuitable for use with Bluetooth headsets. Additionally, incorporating the antenna into the headsets has required extra components, resulting in an increased bill-of-materials and higher costs.
Using its fractal antenna technologies, Fractus has designed an internal FM antenna that offers reduced size, simple integration into a device and a good level of performance in terms of gain and efficiency. The antenna has been produced using low cost surface-mounted technology (SMT), eliminating the need for new manufacturing processes or materials. FracFM is 50 ohm terminated, linear polarized and omnidirectional - as well as RoHS compliant.
Samples and demo boards are available upon request.
