WIPO Patent Application WO/2020/054663

Kind Code:

A1

Abstract:

This resonator has a shield case (10), a first resonance element (11), and a second resonance element (12). The shield case (10) is configured to include a first conductor (13) positioned on the negative z-direction side, and a second conductor (14) positioned on the positive z-direction side, the shield conductor (10) having a hollow space (19) in the interior thereof. The first resonance element (11) has a columnar shape, is arranged within the hollow space (19), has the negative z-direction end joined to the first conductor (13), and has a gap between the positive z-direction end and the shield case (10). The second resonance element (12) is positioned inside the hollow space (19), has the positive z-direction end joined to the second conductor (14), has a gap between the negative z-direction end and the shield case (10), and is a cylindrical dielectric surrounding the first resonance element (11) with a gap open with the first resonance element (11).
