Dielectric lens antennas are effective to produce highly shaped beams that can enhance the performance of wireless broadband communication systems. Beam shaping is used to reduce multi-path interference that causes fading and delay spread, and to enhance gain so that the received power level is compatible with the requirements of high data rate transmission. This paper presents an overview of the design, and measured performance of some examples of dielectric lenses that
can be used in typical scenarios of wireless broadband
communication systems. The paper also addresses the radiocoverage produced by these antennas. The lenses are based on a single basic configuration where the feed is embedded in the lens body. This antenna configuration is flexible enough to accommodate different target beam shaping specifications.
