Design of Compact Rotman Lens with Wide-angle Scanning Using High Permittivity Substrate

This paper presents a compact Rotman lens with wideband wide-angle scanning capability based on a Taconic RF-10 high dielectric constant substrate and different array port sizes. Thirteen different beam ports were carefully designed to enable broadband and wide-angle scanning. The total insertion loss of the proposed solution is better than 5.5dB from the simulation results, and it has the wide-an...
