This paper presents FDTD simulation and measurement results for a microstrip-fed Yagi-Uda slot array antenna used for surface wave excitation of a dielectric slab. Parameters investigated are input return loss, surface wave field profiles, front-to-back ratio and mutual coupling. The FDTD simulation not only confirms the design philosophy of our planar dielectric quasi-optical (PDQ) power combiner, but also provides a powerful CAD tool for its practical design and optimization at millimeter wavelengths
