摘要: In an ultra-wideband (“UWB”) communication system comprising a pair of UWB transceivers, an asynchronous two-way ranging method for closely estimating the time-of-flight between the transceivers after the exchange of only 3 messages between the transceivers. In an alternate asynchronous two-way ranging method, the time-of-flight between the transceivers may be closely estimated after the exchange of only 4 messages between the transceivers.

摘要: A compact, wideband antenna system includes first and second monopole radiating elements positioned near an edge of a common ground plane. The first and second monopole radiating elements may be located on opposite sides of the ground plane. Additional monopole elements may also be provided. In some embodiments, the ground plane includes an opening in a central region thereof to accommodate an optical system. In some embodiments, an additional antenna (e.g., an array antenna) may be provided over the same ground plane in a region between the monopole elements.

摘要: An antenna assembly having a pair of feed conductive elements directed in divergent directions, with each pair of conductive elements including a conical sheet conductor and a cylindrical sheet conductor, and radiating wire conductors extending away from each cylindrical sheet conductor. A balun feed system is defined between the pair of conical sheet conductors. A plurality of ferrite-cored inductors are provided on the wire conductors. A tubular radome assembly protects at least the radiating wire conductors from damage from external forces.

摘要: 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.
