This study reports the dielectric and structural characterisation of composites formed by the mixture of a BiVO₄ ceramic matrix with ZnO (25, 50, and 75 wt.%) obtained through a solid-state method procedure for applications in the microwave range. X-ray diffraction is used for structural characterisation. The dielectric properties and temperature coefficient of resonant frequency indicate a composition with ZnO close to zero. Dielectric constants varying with ZnO composition (7 to 67) and dielectric loss of ~ 10⁻² are measured, and the results confirm that the ZnO can improve the thermal stability of the composites. The composites are analysed as dielectric resonator antenna, where the experimental and theoretical characteristics of the resonator, like return loss, bandwidth, and input impedance, are in good agreement. Experimentally, for the BiVO₄ reference sample, bandwidths of 12.5% and 40.82% are found for the addition of 75 wt.% ZnO for a frequency operation of ~ 5.52 GHz.

这项研究报告了BiVO ₄陶瓷基体与ZnO（25、50和75 wt。％）的混合物通过固态方法获得的复合材料的介电和结构表征，该方法可在微波范围内使用。X射线衍射用于结构表征。介电性能和谐振频率温度系数表明ZnO接近于零。介电常数随ZnO组成（7至67）和〜10 ^-2的介电损耗而变化测量结果表明，ZnO可以改善复合材料的热稳定性。该复合材料被分析为介质谐振器天线，谐振器的实验和理论特性（如回波损耗，带宽和输入阻抗）非常吻合。实验上，对于BiVO ₄参考样品，在〜5.52 GHz的频率下，添加75 wt。％ZnO的带宽为12.5％和40.82％。
