Abstract :
In mobile communication and ITS services, antennas are required to have beam shift and low sidelobe characteristics in order to avoid interference. At millimeter wavelength, dielectric lens antennas are considered promising because of their mass productivity and low costs. In this paper, various shaped lens antennas of low sidelobe characteristics are designed. Sidelobe level changes according to off focus feeds are studied.
