Broadband miniature quadrature coupler on planar cells

Due to the fact that microwave devices at low frequencies are cumbersome, their designs undergo a miniaturization procedure. This work is aimed at exploring the possibilities of miniaturization of a passive broadband power divider. Through the use of planar cells, it was possible to reduce the area occupied by the divider on the printed circuit board from 3786 mm

to 1004.2 mm

. However, miniaturization reduces bandwidth by 10%.
