The dielectric resonator method is now widely accepted as a precise measurement method for determining the dielectric properties at microwave frequencies. This paper describes the measurement results of εr, tan δ and TCf determined by a round robin test of this method. The resultant measurement errors were Δεrr0.10%, Δtan δ0.5105 and ΔTCf0.5 ppm/K, where Δdenotes a standard deviation. The causes of measurement errors and the conditions to improve the measurement accuracy are discussed.
