Abstract
A volume efficient resonator (100) includes a helical coil transmission line (108) fabricated on a plurality of dielectrics (212, 214, 216, 218, 220, 222, 224, and 226). The transmission line (108) includes selectively metalized areas (210) on the dielectric layers. The metalized areas are formed in half loops and interconnected at alternate terminals via through-holes (203 and 205). A distributed capacitor (106) is added to the transmission line (108) using another set of selectively metalized areas (208). The distributed capacitor (106) is shunted to a ground plane (202) via through-holes (204, 206).
