Description of the Related Art As a dielectric material used for a dielectric resonator or a microwave integrated circuit substrate, it is necessary to have a high relative dielectric constant in order to reduce the size of the element or circuit. It is necessary that the Q value be high in order to reduce the loss at the point.

It was difficult to do. Therefore, when these materials are used as a dielectric element in a microwave circuit, the loss increases or the temperature measurement of the circuit itself is compensated, and the temperature change of the entire circuit cannot be reduced to zero.
