COMPARISON OF THE MINIATURIZATION EFFICIENCY OF THE COUPLER USING THE BENDS OF QUARTER-WAVE SEGMENTS

Abstract

This article analyzes the efficiency of microstrip bending line for miniaturization compared to artificial transmission lines. Simple bending of the line allows to reduce the area of the coupler only by no more than 50%, this is due to the limited space inside the coupler. While the artificial transmission lines can provide a reduction in the area of more than 60%.
