Add to ORKGAbstract—A topology for a 3-dB broadband and small-size ring coupler is proposed. It consists of fully-distributed Composite Right-/Left-Handed phase shifters and a Lange coupler. For the fabricated coupler, the frequency bandwidth is one octave, centered on 1.5GHz, while the footprint area is reduced to 25%, compared to the conventional ring coupler topology. The experimental results are in good agreement with the expected ones, obtained by electromagnetic simulation. 1
