Abstract
Radiation synthesizer systems provide efficient wideband operation with loop antenna elements which are small relative to operating wavelength. Energy dissipation is substantially reduced by cycling energy back and forth between a high-Q radiator and a storage capacitance under control of a switching circuit. Systems using multi-segment loop antennas match input impedance to switching circuit parameters. Use of such antennas in crossed-loop configurations excited in quadrature and supported on a wearable garment provide body-borne antennas with isotropic type coverage. With light-weight flexible construction, a wearable radiating system can avoid any need for visually identifiable features and provide effective antenna pattern coverage regardless of the wearer's body orientation, whether standing, prone or otherwise.
