Abstract
A high-directivity directional coupler includes a mainline metal segment and at least one coupling metal segment. The mainline metal segment is an equal-width transmission or delay line with an impedance the same as a system characteristic impedance and the at least one coupling metal segment comprises a continuous coupling line. The coupling line includes two metal segments having a coupling effect with the mainline metal segment, and a metal segment having no coupling effect with the mainline metal segment. The metal segment without coupling effect is equal-width and used for connecting the two metal segments with coupling effect that are metal lines with gradually changing widths, or metal lines comprising a plurality of coupling lines and delay lines alternately arranged.
