A capacitor having a floating plate-shaped electrode, at least two patterned plate electrodes overlying the floating plate-shaped electrode, and a dielectric layer between, is described. The resulting structure exhibits high two-part insertion loss even at frequencies as high as 10 GHz. Notably, the capacitor exhibits an insertion loss of more than -40 dB over a range from 1 GHz to 10 GHz.
