This study investigated the microwave dielectric properties of Sr3(VO4)2 ceramic with 1% B2O3 in the TE01δ mode by employing a meticulously characterized Sr3(VO4)2 ceramic as the dielectric resonator (DR) for the design of a cylindrical dielectric resonator antenna (CDRA). The Sr3(VO4)2 ceramic has a dielectric permittivity ( \(\:{\varvec{\epsilon}}_{\varvec{r}}\) ) of 16.67, a loss factor (tan ẟ) of 0.0005, a temperature coefficient ( \(\:{\varvec{\tau}}_{\varvec{f}}\) ) of 39 ppm/°C, and a density of 4.25 g/cm3. The CDRA comprises a microstrip line integrated with a coaxial probe or subminiature coaxial cable (SMA) connector, which feeds the CDRA, with adjustments made to optimize signal coupling from the transmission line to the DR. A parametric analysis explores how the performance of the CDRA varies with the DR positioned at different substrate locations, altering the overlap distance with the transmission line. Subsequently, an optimized CDRA design is fabricated and thoroughly characterized using a vector network analyzer (VNA) alongside a reference antenna. Comparisons between the simulated and experimental observations encompass the resonance frequency, impedance bandwidth, voltage standing wave ratio (VSWR), and far-field radiation patterns. The fabricated CDRA resonates at 7.68 GHz with an S11 of -29.57 dB, a VSWR of 1.06, and an impedance bandwidth of 10.41%. This comprehensive investigation underscores the successful design, simulation, and characterization of the Sr3(VO4)2 CDRA, demonstrating its potential for microwave applications.
