Miniaturization of microwave devices such as couplers, filters, switchers etc. is an important practical problem due to the tendency of integration of portable and small high-frequency electronics. This article is dedicated to the investigation of the central frequency influence on the miniaturization efficiency of a microstrip branch-line coupler. Simulation of couplers with central frequencies of 1000, 1500, 2000, 2500 and 3000 MHz was made to obtain transmission coefficients. Analysis of the simulation results is conducted.
