摘要: Abstract This paper presents the design of a cylindrical dielectric resonator antenna (DRA) using nearly temperature stable composite material. By combination compounds with positive and negative coefficient, series (1 − x )(Mg 0.95 Zn 0.05 )TiO 3 − (Ca 0.8 Sr 0.2 has been developed. The structural morphological properties grown samples have characterized by means X-ray diffraction (XRD), scanning electron microscope (SEM) energy dispersive (EDX) spectroscopy analysis. Microwave investigated TE 01 δ method. Relative permittivity ( ɛ r ) 21.9, loss tan 0.0002 coefficient resonant frequency τ f −0.15 ppm/°C obtained for = 0.08 sample, which was used designing DRA. DRA resonates at 4.6 GHz offers bandwidth 315 MHz. characteristics proposed simulated Ansoft high structure simulator (HFSS). Comparison between measured results shows reasonably good agreement.
