Filtering Antennas and Filter-Valve Circuits
Some methods of coupling together many circuits or antennas giving them simultaneous excitation from the same source of energy are described. The purpose of such arrangements is the construction of practical filter circuits (filtering antennas) giving square-topped resonance curves with good efficie...

Zusammenfassung: | Some methods of coupling together many circuits or antennas giving them simultaneous excitation from the same source of energy are described. The purpose of such arrangements is the construction of practical filter circuits (filtering antennas) giving square-topped resonance curves with good efficiency. Some interesting phenomena with coupled antennas are described. |
