Abstract : A dual lens antenna design concept is investigated for the limited electronic scanning application. The antenna consists of an aperature lens, a focal field matching lens, and a phased array feed system. The main objective of the design concept is to achieve good pattern control over a limited angular scanning sector with a minimum number of control devices. It is concluded that the antenna design is theoretically feasible for the limited electronic scanning and other antenna applications. In addition, the antenna design has a number of basic advantages in comparison with other existing limited scan antennas. These include the minimum aperture size requirement, the small number of control devices, and good pattern control. The results of the analytical study indicate that a further design effort on hardware implementation aspects is warranted. Specific recommendations are made. (Author)
