Abstract
An automated open resonator system is designed and constructed to operate at 60 GHz for loss tangent and permittivity measurement of materials with loss tangent value as low as 10 micro-radians. This is accomplished by the use of a high Q cavity together with a synthesized 60 GHz Gunn oscillator source, a 56 GHz Gunn local oscillator both phase locked to a frequency standard and the heterodyne detection.Keywords
