Patent ID: 7742793

Claim:
A resonator apparatus, for use in filters for an electrical signal, comprising: a. a first resonator device having a first end and a second end, wherein the first end defines a first segment aligned along a first axis and the second end defines a second segment aligned along a second axis, the first axis being non-collinear with the second axis; b. a second resonator device; and c. wherein the first end and the second end are arranged and configured to lie on the same side of the first resonator and proximate the second resonator, and wherein a first distance of the first end from the second resonator creates a primary coupling between the first and second resonators, and a second distance and a length of the second end creates a secondary coupling between the first and second resonators, wherein the first distance and the second distance do not equal one another, the second end is not physically connected to the second resonator, and the overall distance of the first and second resonators from one another is optimized by independently controlling the primary or secondary coupling.
