Comparison Of Measurement Methods For Characterization Of 3d Printed Lowloss Artificial Dielectric Substrate Based On Cross Unit Cell

This paper deals with the effective complex permittivity determination of low-loss 3Dprinted artificial dielectric substrate based on a cross unit cell. The two resonators working withTE011 and TM010 modes suitable for a uniaxial anisotropy determination are compared with thetransmission / reflection waveguide method. To evaluate the methods’ performance, the eigenmodeanalysis is carried out to provide precise reference values
