[IEEE 2018 IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition (iWEM) - Nagoya (2018.8.29-2018.8.31)] 2018 IEEE International Workshop on Electromagnetics:Applications and Student Innovation Competition (iWEM) - E-Plane Beam-Forming Performance of Rotman-Lens in Multi-Layer Substrate
摘要： A two-dimensional Rotman-lens feeding circuit was proposed for planar two-dimensional multi-beam antenna using multi-layer substrate integrated waveguide in the millimeter-wave band. In this work, an E-plane Rotman-lens for two-dimensional Rotman-lens was designed and the E-plane beam-forming performance was evaluated by array factors from the simulated S-parameters.

摘要： Substrate Integrated Waveguide (SIW) is a low loss transmission line which can be used to connect an antenna to a backed RF circuit in the millimeter wave band. A multi-layer substrate is effective to integrate RF circuits and antennas. Therefore, a transition between a hollow waveguide and a SIW in multi-layer substrate is necessary. However, reflection loss generates at the connections between the hollow waveguide and the SIW in each layer. In this study, a back short and window structures are proposed to use for matching circuit in the transition. Transitions from hollow waveguide to SIWs in multi-layer substrate were designed for low loss over wide bandwidth.
