Abstract
Apparatus for humidity measurement employing a dielectric resonator consisting essentially of a metallic guard, a solid dielectric material, an input antenna and an output antenna. Method of measuring humidity comprising feeding a microwave energy of swept frequencies to the input antenna of said appratus, recovering said energy as a microwave power from the output antenna, and then determining the humidity of the gas through which the microwave energy travels from one antenna to the other, the value of humidity being based on the frequency characteristic of said microwave power.
