A high frequency resonator circuit and method of fabrication is described
which has a resonant frequency independent of physical resonator
dimensions. The resonator operates in a zeroeth-order mode on a composite
right/left-handed (CRLH) transmission line (TL). The LH wave properties
of the CRLH-TL contributing anti-parallel phase and group velocities. In
one variation, the unit cells are formed from microstrip techniques,
preferably creating alternating interdigitated capacitors and stub
inductors. The resonant wavelength of the resonator is dependent on the
electrical characteristics of the unit cells and not the physical size of
the resonator in relation to the desired resonant wavelength. The
resonator is created with at least 1.5 unit cells and the Q of the
resonator is substantially independent of the number of unit cells
utilized. The resonator circuit is particularly well suited for reducing
resonator size, and allows resonators of various wavelengths to be
fabricated within a fixed board area.
