SOL-GEL PREPARATION & CHARACTERIZATION OF ZnCaAl2O4 CERAMIC NANOPARTICLES
Microwave dielectric materials are well-recognized for their broad application in communication from satellite to ground. The advantages of dielectric materials lie in scaling down the device and the controlled dielectric permittivity. However, the growing world of communication is expanding its operating frequency for the global position satellite (GPS). Presently, the trend of miniaturization of patch antenna has been demanded to fulfill the requirement of the GPS system. In this perspective, dielectric ceramic materials have got recognized due to the tunability of dielectric permittivity and quality factor to a great extent. In this work, we report the synthesis and characterization of ZnCaAl2O4 ceramic nanoparticles for their application as the patch antenna material.
