Abstract
Microwave dielectric materials are well-recognized for their broad application in communication from satellite to ground. The advantages of dielectric materials lie 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 calcium zinc aluminate (ZnCaAl2O4) composite nanoparticles. XRD investigation endorsed the mixed phases of ZnCaAl2O4, and ZnA2O4 in the prepared sample. FTIR study demonstrated the various compositional transmittance peaks correspond to the compound nanoceramic material ZnCaAl2O4. SEM analysis showed the agglomeration of nanoparticles with their average diameter of 50 nm whereas the presence of Zn, Ca, Al, and O are confirmed by the EDS investigation.
