ABSTRACT:
A resonator comprises two dielectric substrates. A ground electrode and a U-shaped pattern electrode are formed respectively on the two surfaces of the first dielectric substrate. A take-out electrode is drawn out at a certain distance from one end of the pattern electrode, and is connected to the take-out terminal electrode. A guard electrode is formed opposite to the other end of the pattern electrode. A shield electrode is formed on a second dielectric substrate. The pattern electrode, the ground electrode and the shield electrode are connected by a terminal electrode. In addition, the guard electrode, the ground electrode and the shield electrode are connected by a terminal electrode. A chip-type filter can be obtained by forming a plurality of pattern electrodes on an dielectric substrate, and coupling them electromagnetically.
