Comparison between measured and simulated directivity of a tilted beam high efficiency MTS antenna realized with printed grain of rice-shaped elements. The antenna has been designed to radiate a RHCP beam tilted 30° from broadside at 20 GHz. (a) Co-polar component, (b) cross-polar component: comparison between simulated and experimental results; (c) Details relevant to the aperture implementation and the feeder structure.
