A novel rotman lens in SIW technology

摘要

This paper presents a novel Rotman lens in low-cost Substrate Integrated Waveguide (SIW) technology. An original solution is proposed for the design of the adsorbing load at the sidewalls of the lens and for the phase-shifters at the output ports. A three beam prototype feeding an 8-element array working at Ku band has been fabricated and tested.
