  • Highly isolated circular polarized antenna
    Patent number: 7605758
    Abstract: An antenna featuring a pair of radiating elements. Each pair of radiating element is fed from the same input. Each radiating element is a stacked antenna made of feeding patch and radiating patch featuring cross recessed corners. Moreover, the corners of a radiating patch and the corners of its feeding patch are cut in opposite directions. The use of recessed corner patches result in improved cross-polarization. Improved cross-polarization leads to better isolation between radiating elements of an array antenna and to an antenna featuring improved isolation from its surroundings.
    Type: Grant

  • Method and device for adjacent channels operation
    Patent number: 7542752
    Abstract: A method and device for adjacent channels operation based on downconverting the input signal to an IF signal, filtering the IF signal, and upconverting the filtered IF signal to the original frequency. The present invention is primarily directed to applications involving the use of standard RF transceiver which does not incorporate a high Q filter. Moreover, the present invention may be used with a circular polarized cross recessed corners stacked array antenna in order to further improve its adjacent channels operation performance.
