Publication number: 20090002248Abstract: The present invention employs slot antennas to make UWB antenna and a quarter-wavelength slot UWB antenna for use in mobile terminals. The slot length, which is related to the lower resonant frequency, is about half (for the half-wavelength slot antenna) or quarter (for the quarter-wavelength slot antenna) of the wavelength, while the higher resonant frequency is related to a dimension of the tuning stub. By modifying the dimensions of the tuning stub, good impedance matching of the antenna can be achieved according to the desired operating frequency. This invention can be used for mobile terminals to transmit and receive UWB signals in the frequency range of 3.1 GHz-4.9 GHz.Type: ApplicationFiled: October 13, 2004Publication date: January 1, 2009Inventors: Anping Zhao, Jussi Rahola

Publication number: 20070085754Abstract: A transceiver system having an RF front-end operatively connected to two separate non-50 ohm antennas for separately providing transmission/reception paths for 1 GHz band and for 2 GHz band. A switching module is operatively connected to each antenna for mode and frequency-range selection within each band. Each switching module has a plurality of switching elements connected to a plurality of signal paths. Matching is separately and independently provided for each signal path.
