Compact Branch Line Coupler using Step Impedance Transmission LinesSITLs

A compact branch line coupler is proposed by using the optimized Step Impedance Transmission Lines (SITLs). The proposed branch line coupler has an area reduction of morethan 50% at 1GHz. The measured results of the fabricated power coupler are in good agreement with the simulation results.
