Abstract:
A resonator configured to resonate in the TE.sub.0.gamma..delta. mode at a lowest resonant frequency having a wavelength .lambda. in empty space, said resonator comprising: a dielectric resonator disk configured to exhibit an effective dielectric constant .epsilon..sub.re, said disk having first and second opposing ends along an axis and a closed curve wall surrounding said axis and extending between said first and second ends, said disk having a hole penetrating therein from said first end and extending toward said second end, wherein at least one of said first and second ends serves as a boundary between said disk and a dielectric material having a dielectric constant less than 0.5.epsilon..sub.re ; and a conductive wall juxtaposed with said curved wall of said disk and positioned less than 0.75.lambda./.epsilon..sub.re from said axis.
