Abstract

This study invstigates the dielectric properties and potential applications of YTaO₄ electroceramic in microwave (MW) and radiofrequency (RF) devices. The monoclinic YTaO₄ phase (I12/a1) was synthesized via a solid-state reaction and confirmed by X-ray diffraction and Raman spectroscopy. The electroceramic exhibited moderate permittivity (ε’ = 11.01), low loss tangent (tan δ = 9.53 × 10⁻⁴), and excellent thermal stability, as evidenced by a near-zero temperature coefficient of resonant frequency (τ_f = -18.69 ppm·°C⁻¹). To evaluate its performance in MW applications, dielectric resonator antennas (DRAs) were fabricated and tested, achieving a reflection coefficient (S₁₁) of −41.84 dB, bandwidth of 55 %, radiation efficiency of 99.45 %, and gain of 6.0 dBi. These results demonstrate YTaO₄′s potential as a thermally stable and efficient material for MW and RF applications.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
