Design and Implementation of a Novel Directional Coupler for UHF RFID Reader [PDF]
Electronics, 2016 The directional coupler is applied to isolating RX from TX because of low cost and simplicity compared to the circulator in the radio-frequency identification (RFID) reader. Because of unequal phase velocity between odd and even mode, the drawback of the

A six‐port network based on substrate integrated waveguide coupler with metal strips
IET Microwaves, Antennas & Propagation, 2022 In this study, a novel coupling structure based on half‐mode substrate‐integrated waveguide (HMSIW) is proposed with a small size and broad bandwidth. The HMSIW coupler is realised by connecting their equivalent magnetic walls with metal strips, which ...

Scattering parameters of a non-reciprocal magneto-optical integrated coupler used as an isolator [PDF]
EPJ Web of Conferences, 2022 We theoretically investigate a non-reciprocal magneto-optical integrated slab directional coupler. The scattering parameters of the structure are derived in the frame of the Coupled-Mode Theory (CMT).
