Microwave Dielectric Properties of Antiferroelectric Lead Zirconate

Abstract

The dielectric properties of ceramic lead zirconate and rutile are presented at microwave frequencies. Several techniques are required to span the frequency range from 100 Hz to 26 GHz, and rutile is utilized as a reference material to determine the consistency between measurement methods. A significant relaxation was seen for lead zirconate. At 10 GHz, the dielectric constant decreased 20% from the 1‐MHz value of 160, and the dielectric loss increased by more than 3 times the low‐frequency value of 0.007.
