Patent ID: 7391288

Claim:
A resonator apparatus, comprising: a resonator formed from a composite high frequency right/left-handed transmission line; said resonator having an input port for coupling a high frequency signal into said resonator; said resonator having an output port for coupling a high frequency signal out of said resonator; wherein said transmission line is configured to resonate at the zeroeth-order characterized by an infinite-wavelength wave in the transmission line; wherein said transmission line has a resonant frequency which is independent of the physical size characteristics of the resonator; wherein said transmission line is formed from unit cells having a desired equivalent shunt inductance, shunt capacitance, series inductance, and series capacitance, within said transmission line; and wherein left-handed aspects of said composite high frequency right/left-handed (CRLH) transmission line have an equivalent series capacitance and shunt inductance, while right-handed aspects of said composite high frequency right/left-handed (CRLH) transmission line have an equivalent series inductance and shunt capacitance.
