Abstract
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 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> to 1004.2 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . However, miniaturization reduces bandwidth by 10%.
