Radiation synthesizer systems and methods

摘要: Synthesizer radiating systems provide efficient wideband operation with an antenna, such as a loop, which is small relative to operating wavelength. Energy dissipation substantially reduced by cycling energy back and forth between high-Q radiator storage capacitor. Wideband achieved actively controlling power switch devices. Dissipation further during high speed switching use of sequential methods avoid capacitively stored in capacitances, including control circuit capacitance. Systems using multi-segment loop antennas are arranged match antenna input impedance parameters. Personal transmit/receive mounted on jacket or other clothing for field enabled.
