N2 - This paper presents a novel MEMS comb-structured variable capacitor at 20GHz that features a wide capacitance tuning range of 200%, yet avoids unwanted coupling through the springs. This new varactor consists of three comb structures - two of which are anchored to the substrate, while the third, which capacitively couples the two anchored ones, is movable, suspended on mechanical springs. This new design decouples the mechanical mechanism from the RF capacitor and allows an independent optimal design of the two.
