Quad Band GSM Antenna Which Fits Within GPS Based Locators
fractus, a developer of fractal antenna technology says that it has developed a dual-mode ISM and GSM quad band antenna that can be shaped to the mechanics of a GPS emergency device. A key challenge associated with currently available GPS emergency devices is their poor in-building coverage, making it difficult to locate people when they are at home or in a hospital, for example. By adding the ISM900 band, fractus has enabled emergency devices to also locate people indoors. The GSM quad band connectivity allows emergency calls to be placed from the device as well. more

fractus, a developer of fractal antenna technology says that it has launched a family of internal passive DVB-H antennas that enable mobile TV capable phones that will be far smaller than current DVB-H devices. The move toward implementing DVB-H in mobile handsets brings a new set of challenges for RF designers and handset manufacturers. DVB-H operates on a lower frequency than traditional cellular systems - 470MHz-862MHz - as well as utilising a broader bandwidth. It therefore requires a much larger antenna than is used for either 3G (1900-2025MHz & 2110-2200MHz) or GSM (890-915MHz & 1710-1785MHz) systems. more
