Abstract
The present invention discloses an integrated circuit (IC) 200 including a plurality of microstrip conductive lines, i.e., 210, 220, 230, and 240. The IC includes a phase shifting means wherein the plurality of microstrip conductive lines, i.e., 210, 220, 230, and 240, may have different or equal lengths forming a coplanar phase-shifting assembly for shifting phase of the electromagnetic wave transmitted therein. The conductive lines, i.e., 210, 220, 230, and 240, are configured substantially rectangular in shape. The IC 200 also includes a decoupling means 280 for substantially decoupling and reducing the interference between the electromagnetic fields of the conductive lines, i.e., 210, 220, 230, and 240. The decoupling means 280 is a conductive means disposed inside the rectangular shape surrounded by the four conductive lines, i.e., 210, 220, 230, and 240, of the phase-shifting assembly. The decoupling means 280 and the microstrip conductive lines, i.e., 210, 220, 230, and 240, are configured such that the major operational characteristics of the phase shifting means are substantially compatible with the phase shifting means without the decoupling means under a presumptive no interference condition.
