Abstract. This article describes a range of compact power dividers - quarter-wave directional couplers, ring divider and Wilkinson coupler. Power dividers in their standard design can take up a significant area at low frequencies. This can adversely affect their use in some applications. Therefore, to eliminate this drawback, instead of the usual sections, we used artificial transmission lines, which consist of inductance and capacitance in a microstrip design. Using this approach, constructions of compact divisors were obtained. So the directional coupler on such lines has an area of 78.8% less than that of a conventional design, a ring divider by 80.3% and a Wilkinson coupler by 67.7%. For all compact designs, a negative point should be noted - this is a narrowing of the frequency band.

Key words: material, microstrip line, dielectric, substrate, miniaturization.
