Abstract

A resonator having increased isolation includes a first resonator having first characteristics, and configured to resonate with another resonator having the first characteristics; and a second resonator having second characteristics, and configured to resonate with another resonator having the second characteristics; wherein the resonator has an arrangement and a structure that minimizes a coupling between the first resonator and the second resonator.
