Abstract: The application of ray-tracing for the efficient analysis of curved leaky-wave antennas combined with shaped dielectric lenses is presented in this work. Thanks to the ray-tracing technique, based on geometrical optics, the phase and amplitude of the fields at the lens aperture is obtained with low computational load. This computation also takes into account the reflections due to the change of media between the lens and the air. With this, the far-field radiation pattern is accurately and efficiently calculated using Kirchhoff's scalar diffraction theory. The results are validated against full-wave simulations, achieving a significant time reduction above 99%.
