| Abstract Scope |
This presentation exhibits the work to fabricate high density strontium-tantalum based oxide ceramics for integration into miniaturized dielectric resonator antennas (DRA) applicable for use in 5G devices. The effect of various sintering conditions on the microstructure, relative density and phase purity are investigated. Through these optimizations, the relative density of (Sr,La)2(Ta,Ti)2O7 and β’-SrTa2O6 ceramics have been increased from ~ 80% up to 94%. These characteristics are coupled with low frequency dielectric measurements of the permittivity and losses, conducted via a metal-insulator-metal structure. Results of high frequency measurements performed within a resonant cavity around 3.5 GHz are also presented. The results demonstrate that optimal processing conditions to attain high relative density strontium-tantalum based ceramics improve the dielectric performance and suitability for 5G DRA applications. |
