摘要
A TE0&ggr;&dgr; mode dielectric resonator (12) includes a cylindrical dielectric disk (32, 32′, 32″) having top and bottom ends (20, 22) spaced apart by a closed curve wall (24). The dielectric disk has an effective dielectric constant greater than 40. An axially aligned hole (36) is formed through the disk (32) between the top and bottom ends (20, 22). A conductive wall (34, 34″) is formed at or slightly beyond the wall (24) but does not cover the top and bottom ends (20, 22). The hole (36) has a preferred diameter between 0.21 and 0.4 times the diameter of the disk (32, 32′, 32″). The disk may be configured as a heterogeneous composite of dissimilar materials which exhibit increasing dielectric constant at increasing radial distance and increasing Q at decreasing radial distance.
