Abstract
The Sr3MoO6 (SMO) double perovskite has been studied due to its
photoluminescence properties. Herein, the aim of this work is to study
the dielectric properties of the SMO in radiofrequency (RF). From
impedance spectra, we proposed an equivalent circuit using three
associations of R-CPE in parallel. We also evaluated its performance as
a microwave device (dielectric resonator antenna - DRA). The SMO-based
DRA operated at 3.71 GHz (frequency of operation antenna), with
reasonable gain (5.00 dBi) and directivity (5.70 dBi), where these
values are close to the ones presented by commercial antennas.
Additionally, a numerical simulation is performed to obtain the main
parameters for proper device application. Based on our results, SMO
electroceramic shows important properties, which can be used for devices
operating in the S-band such as weather radar, surface ship radar and
communications satellites. (C) 2018 Elsevier B.V. All rights reserved.
