20100123531 | Resonator Tuning - A resonator system contains one or more resonator, and has a plurality of degenerate resonant modes. Switching circuitry can be operated for controlling a degree of coupling between the resonant modes, such that resonant properties of the resonator system can be controlled. Where the resonator system includes one resonator, the size of a notch in a conductive patch can be controlled to vary the coupling between the resonant modes within that resonator. Where the resonator system includes multiple resonators, the coupling between the resonant modes in the resonators can be varied. A single device can be tuned as required, in order to provide the desired frequency response properties. | 05-20-2010 |
