Characterization of dielectric constants and dissipation factors of liquid crystal polymer in 60–80 GHz band

We have successfully applied the overmoded circular cavity measurement approach to characterize dielectric constants and dissipation factors of LCP in the 60-80 GHz band of increasing application. Compared to the only publically available measured data in this band, our measured dielectric constants differ considerably (but are close to the data at a lower frequency from the supplier [3]); while our measured dissipation factors are in good agreement.
