PRECISION STANDING WAVE DETECTORS FOR WAVEGUIDES.

Abstract

It is possible to build a precision standing wave detector for waveguides by using line stretchers. With it, standing wave ratios as near unity as 1.001 can be detected, and correspondingly larger ones measured with good accuracy. Larger standing wave ratios (as large as 5) can be measured with an accuracy of several percent or better. This type of standing wave detector, because it is considerably larger and requires a better probe amplifier, seems less well adapted for field use than the movable-probe type of standing wave detector. However, its superior accuracy makes it an ideal laboratory instrument. It should be particularly advantageous for the higher frequencies, where minute dimensions make an accurate movable-probe type of instrument exceedingly difficult to construct. (Author)
