Abstract

The microwave dielectric properties of Nd(Ti0.5−xZrx)W0.5O4 ceramics were examined with a view to their application in mobile communication. The Nd(Ti0.5−xZrx)W0.5O4 ceramics were prepared using the conventional solid-state method. Dielectric constants ( $${\varepsilon _r}$$ ε r ) of 15.4–19.4 and quality factor (Q × f) of 3600–11,100 GHz were obtained for NdTi0.5W0.5O4 ceramics at sintering temperatures in the range 1425–1525 °C for 4 h. A maximum density of 6.68 g/cm3 was obtained for the Nd(Ti0.47Zr0.03W0.5)O4 ceramic, sintered at 1500 °C for 4 h. A Nd(Ti0.47Zr0.03W0.5)O4 ceramic that was sintered at 1500 °C for 4 h had a dielectric constant ( $${\varepsilon _r}$$ ε r ) of 19.8, a quality factor (Q × f) of 17,300 GHz, and a temperature coefficient of resonant frequency ( $${\tau _f}$$ τ f ) of − 54 ppm/°C. The proposed patch antenna sensor had a sensitivity of 0.112 MHz/°C.
