E-plane Beam-forming Performance of Rotman-lens in Multi-layer Substrate

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. The two-dimensional multi-beam feeding circuit is composed of series connection of H-plane and E-plane Rotman-lenses...

Description
Summary:	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. The two-dimensional multi-beam feeding circuit is composed of series connection of H-plane and E-plane Rotman-lenses which are designed independently. 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.
