Design of a Hybrid Directional Coupler in Empty Substrate Integrated Waveguide (ESIW)
IEEE Microwave and Wireless Components Letters, 2015 This letter shows the procedure of design of a hybrid directional coupler based on Empty Substrate Integrated Waveguide (ESIW). Once proved in previous works the feasibility of ESIW and the good performance indexes this technology can achieve, the following step is designing useful devices to be integrated in planar circuits.
