Abstract
A resonator may include a first dielectric member, a second dielectric member, and a composite member. The first dielectric member may have a first cavity. The composite member may include a piezoelectric layer and may overlap at least one of the first dielectric member and the second dielectric member. At least one of the second dielectric member and the composite member may have a second cavity. The piezoelectric layer may be positioned between the first cavity and the second cavity. A projection of the first cavity in a direction perpendicular to a flat side of the first dielectric member and a projection of the second cavity in the direction may intersect each other to form a polygon. No two edges of the polygon may be parallel to each other.
