Both circular and rectangular waveguide technologies are investigated. The results of the investigation show that single-mode rectangular waveguide implementations offer substantially wider tuning range, as opposed to classical dual-mode circular waveguide implementations. In addition to simulations, measurements are also presented indicating very good agreement with theory, thereby fully validating the CAD procedure.This work was supported in part by MINECO (Spanish Government) under Research and Development Project TEC2016-75934-C4-1-R and in part by Research and Development Technicians under Grant PTA2015-10839-I.Ossorio-García, J.; Vague Cardona, JJ.; Boria Esbert, VE.; Guglielmi, M.
