The microwave dielectric properties of $\alpha$-CaSiO3 and SrSiO3 synthesized by a solid-state reaction were $\varepsilon_{\text{r}} = 6.82$, $Q f = 42{,}200$ GHz, $\tau_{\text{f}} = -18.9$ ppm/°C and $\varepsilon_{\text{r}} = 6.78$, $Q f = 13{,}100$ GHz, $\tau_{\text{f}} = -65.9$ ppm/°C, respectively. (Ca1-xSrx)SiO3 solid-solution series were also synthesized by a solid-state reaction and their microwave dielectric properties were examined. Two structural-type solid solutions were formed in wide range of $x = 0$ to 0.4 and 0.6 to 1.0. Good microwave dielectric properties with $\varepsilon_{\text{r}} = 6.62$, $Q f = 66{,}700$ GHz, and $\tau_{\text{f}} = -40$ ppm/°C were obtained with $x = 0.8$ of the (Ca1-xSrx)SiO3 series.
