Abstract
A novel leaky-wave radiator generating non-diffractive Bessel beams for millimeter waves is presented, based on a reference configuration recently investigated by one of the Authors for microwave applications. For increasing frequency ranges, a suitable higher-order leaky-wave mode is used here in order to overcome fabrication issues and reduce ohmic losses. As a useful design tool, closed-form equations are analytically derived for the considered structure. Full-wave simulation results validate the design equations and the overall proposed approach, thus allowing manufacture and test of a launcher prototype operating at 40 GHz| File | Dimensione | Formato | |
