ANTRUM introduces
       A new split waveguide cavity resonator at 12 GHz

Operates with two specialized resonant irises where the sample is snugly placed in the opening of the split cavity. The opening is adjustable and the thickness of the sample is accurately measured with a digital vernier which is an integral part of the cavity. The cavity needs to be connected to a vector or scalar analyzer and no prior calibration is needed. A bespoke algorithm is then run with inputs, the frequencies and the Qs of the air and sample. The algorithm runs in seconds and estimates the dielectric constant and the loss tangent of the sample. It has an optional learning facility where as more samples measured it logs their parameters for building a customer database.

The sample area is 3 cm x 3 cm minimum and up to 5 mm thickness.
