Microwave, Permittivity, Dielectric Loss Tangent and Transmission Attenuation Measurement System:
System No. RTS04

Model No. rts 04

RTS04 measures relative permittivity (dielectric constant), dielectric loss tangent based on a correlation between measurement frequency and transmission attenuation as the millimeter wave passes through the flat plane sample.
(Measurement value is the average value in the measurement frequency range.)
Despite  its compact dimensions, your sample can be measured with plane wave because the lenses are attached to the antennas, providing high measurement accuracy.
Samples can be smaller than conventional systems because they can be placed in the vicinity of the antennas.
Also, It lets you measure reflection attenuation of electric wave absorber with optional software.

Measurement frequency and sample size

Measurement Frequency 5GHz~26.5GHz
Sample size Less than 300mm x 300mm

Note) The higher the measurement frequency is, the smaller the samples can be.

*By applying the gate beyond the lenses closer to the sample, transmission attenuation and relative permittivity can be acquired by the resolution of 0.1dB and 0.01 respectively, using a standard vector network analyzer with time-domain option.
*Scholar network analyzer, synthesized sweeper also applicable.
