Abstract
A sectored antenna system has one or more dielectric lenses, each having a surface and two or more low profile antenna feed devices. At least one of the feed devices radiate signals into said lens that emerge as separate directional beams, and/or the lenses receive incoming signals from different directions and focus them onto different antenna feed devices. The feed devices of the sectored antenna system are low-profile broadband feed devices, such as log periodic dipole arrays or tapered notch antennas. Special design guidelines are given for their use with a lens. In addition, a method to reduce the cut off frequency of the tapered notch antenna is shown.
