Phase Sensor for R. F. Transmission Lines.
Abstract
This invention relates to a device for detecting the phase on an R.F. transmission line, which is useful for indicating the resonance condition of a complex load impedance (such as an antenna). The device according to the invention does not require any physical connection to the mainline of the R.F. transmission system, nor any wire-wound transformer. Coupling is obtained by a short length of wire parallel and adjacent to the center conductor of the main line. The circuit comprises two diodes connected with like poles to opposite ends of the coupling wire, a resistor between the other poles of the diodes, and a meter across the resistor.
