Abstract :
We have examined the characteristics of multi-beam antenna with vertical fan beam consisting of the dielectric lens and Fermi antennas with corrugation. We have confirmed the good performances of Fermi antennas with corrugation for the feed at 24GHz band through trial manufacturing and evaluation tests. Then the lens shape and feed positions have been designed by Pareto GA, and various radiation patterns of the lens antenna have been examined by numerical simulation. It became clear that the proposed antenna configuration provided superior performances as the multibeam antenna. In the future, we are to manufacture the lens and to evaluate.
