This letter discusses the design and fabrication of a novel fully dielectric five-beam annular grating antenna. The proposed all-silicon genetically optimized antenna works at 77 GHz with a radiation efficiency of 91% and a bandwidth of 5 GHz. The antenna has the advantages of low-cost, planar structure, and ease of fabrication and integration in silicon-platform.
