Abstract
A dielectric waveguide antenna for X-band is designed. A printed dipole fed by a coplanar strip excites the Ex 11 mode inside the dielectric waveguide. The waveguide mode in its turn excites a properly dimensioned patch, which generates the radiation pattern. Simulations are conducted from the stand-alone waveguide up to the complete structure to reveal the coupling and scattering effects between the substrate waveguide and the patch radiator. A pair of prototypes is manufactured and measurements are performed.
