| Abstract: | Shaping techniques are applied to the design of dielectric lens antennas. The aim of shaping is to find a lensprofile that transforms the radiation pattern of the primary feed into a desired amplitude shaped output pattern. This paperpresents a flexible shaping approach that based on geometrical optics(GO),by shaping, the lens antenna can achieve lowside-lobes. |
