  • Tunable antenna with variable series L-C network
    Patent number: 4620194
    Abstract: Emitting and receiving antenna system for accommodating all bands and frequencies and for operating selectively adjustably in resonance at a given emitting or receiving frequency, formed by one antenna component or two counterpart antenna components, each component containing therewithin a variable inductor and a variable capacitor, a drive mechanism for shifting the shiftable inductor part relative to the fixed inductor part of each such inductor for varying the inductance and conjointly for shifting the shiftable capacitor part relative to the fixed capacitor part of each such capacitor for varying the capacitance, and a control mechanism for controlling the drive mechanism for selectively shifting the corresponding shiftable parts conjointly for achieving selective antenna resonance tuning at an exact point corresponding to the desired operating band and frequency, such as with the shiftable inductor part and shiftable capacitor part of each antenna component being connected together for common shifting mo
