  • Patent number: 10218540
    Abstract: One aspect is a circuit for tuning a resonance frequency of an electrically small antenna and directly exciting the electrically small antenna. The circuit includes a first source configured for providing a constant voltage. The circuit also includes an antenna and a switched capacitor configured for being alternatively alternately coupled to the first source to be charged thereby and to the antenna for exciting the antenna. Another aspect is a transmitter for transmitting a wireless signal using an antenna without using a variable voltage source to excite the antenna. The transmitter includes a first source configured for providing a constant voltage. The transmitter further includes an antenna and a switched capacitor configured for being alternately coupled to the first source to be charged thereby and to the antenna for exciting the antenna and for tuning a resonance frequency of the antenna.

  • Publication number: 20190042809
    Abstract: RFID systems are disclosed that include at least one RFID receiver system and a distributed exciter architecture. Exciters can be connected via wired and/or wireless connections to the RFID receiver system, which can control activation of the exciters to detect the presence of RFID tags within interrogation spaces defined by the exciter topology. One embodiment includes an RFID receiver system configured to detect information from RFID tags within a receive coverage area, and a plurality of exciters defining a plurality of interrogation spaces within the receive coverage area of the receiver system. The receiver system is configured to transmit a control signal that identifies one of the exciters and includes information indicative of an RFID tag interrogation signal, the exciters are configured to receive the control signal, and the exciter identified in the control signal is configured to illuminate an interrogation space with the RFID tag interrogation signal.

  • Patent number: 10135650
    Abstract: A circuit for tuning a resonance frequency of an electrically small antenna. The circuit includes a first source configured for providing a modulation signal, a second source configured for providing a periodic electrical signal, an antenna, and a tuning circuit configured for modulating a resonance frequency of the antenna in response to the modulation signal. The tuning circuit includes first and second capacitors that are alternately coupled to the antenna to change the resonance frequency of the antenna. The capacitor currently coupled to the antenna is decoupled from the antenna and the other capacitor is coupled to the antenna when the voltage across the capacitor currently coupled to the antenna is momentarily zero. In an exemplary embodiment, the tuning circuit comprises first and second inductors rather than capacitors. The inductors are switched into and out of the circuit when the current through the currently coupled inductor is momentarily zero.

  • Patent number: 10097217
    Abstract: The present invention provides methods and devices to radiate wideband signals. The devices may include a tunable high Q narrowband antenna having a plurality of ports including a feed port and a tuning port as well as a tuning element coupled to the tuning port of the antenna. One or more voltage sources supply energy for radiating a radio frequency signal. A modulating signal generator may also be provided for generating a high data rate signal coupled at the tuning element for modulating the tuning element.

  • Publication number: 20180261908
    Abstract: A plug-and-play antenna may be used with many different types of wireless communication devices. An antenna may be coupled to an impedance tuning component and a waveform generator. A calibration control module receives radio status information, controls the waveform generator to vary a response of the antenna, and tunes the impedance tuning component to match impedances between a radio and the antenna.
