Abstract: Miniature directional coupler with wide bandwidth consisting of compact structures and curved lines has been developed. The type of structures was chosen in such a way as to achieve the greatest possible coincidence of their characteristics in the bandwidth with the characteristics of quarter-wave sections. The area of the developed coupler is 69.8% less than the area of the same device in its standard version. Device modeling was performed in the Cadence AWR program. It is shown that miniaturization of the directional coupler caused deterioration of such characteristics as operating frequencies band, preservation of the phase differences between the outputs in a wide frequencies band, and attenuation in the band. A model of the coupler was made, which allowed us to confirm experimentally the correctness of calculations in AWR. © Published under licence by IOP Publishing Ltd.
