A method for designing matching networks to reduce the distortion created by nonlinear passive components interfacing with antennas is presented. Coaxial connectors produce passive intermodulation distortion based on the amount of current flowing through them. By increasing the input impedance at the connector using impedance transformations, current, and thereby passive intermodulation distortion,...
Modern electrically steerable antennas have the ability to evolve their far-field radiation pattern on nanosecond timescales. The transient radiation that occurs during this evolution cannot be captured by conventional radiation pattern measurements, which take at least several minutes to complete. We present a temporal and spatial sampling method of measuring the rapid temporal evolution of an electronically...
