Development of microstrip directional coupler of reduced dimensions
Abstract
A compact coupler was developed using microstrip cells installed instead of traditional quarter-wave segments. Using the program of electrodynamic modeling AWR DE 13, its frequency characteristics were obtained. A prototype of the proposed coupler is made, and its characteristics are measured confirming the operability of the device. The area of the compact coupler turned out to be 74 % less than the area of the traditional construction.
