Miniaturized Branch-line Coupler Employing Periodically Arrayed Grounded-strip Structure

In this work, a short guided-wavelength coplanar waveguide employing a periodically arrayed grounded-strip structure (PAGS) is proposed for the first time. Using a coplanar waveguide employing PAGS, a miniaturized branch-line coupler was realized in a ...
Recently, the demand for highly integrated and miniaturized radio frequency integrated circuits (RFIC) has increased in the wireless communication systems market. With the evolution of silicon CMOS device process technology, highly integrated silicon ICs, including RF and base-band block, have been developed. 1 However, passive components such as couplers,...
