摘要: Dielectric lens antennas are proposed for wireless broadband communication systems in the mm-wave range. Two antenna configurations base station applications presented and evaluated terms of radiation characteristics, feeding system, input reflection loss, bandwidth fabrication tolerances. The system requirements to provide optimum power distribution over cell good control boundaries achieved. These designed circular symmetric coverage use a waveguide as feed targeting typical at 60 GHz 40 same concept is applicable non- symmetrical cells with other feeds. Simulations performed using Geometrical Physical Optics codes well Finite Elements codes. Theoretical results verified by measurements, showing agreement.
