Researchers from Shandong University have developed new low-permittivity dielectric ceramics suitable for microwave and millimeter-wave communication. By synthesizing a system incorporating lithium, rare earth elements, and phosphate, they achieved materials with low dielectric constants, high-quality factors, and low density. These ceramics were tested in microstrip patch antennas, showing excellent performance. This work, involving advanced calculations and spectroscopy, aims to enhance wireless communication by reducing signal delays and improving material properties.
