  • ACTIVE ANTENNA ADAPTED FOR IMPEDANCE MATCHING AND BAND SWITCHING USING A SHARED COMPONENT
    Publication number: 20140306859
    Abstract: An active antenna and associated circuit topology is adapted to provide active impedance matching and band switching of the antenna using a shared tunable component. Using a shared tunable component, such as a tunable capacitor or other tunable component, the antenna provides a low cost and effective active antenna solution. In certain embodiments, one or more passive components can be further utilized to design band switching of the antenna from a first frequency to a second desired frequency.
