Abstract

Systems and methods are disclosed which provide aggressively sculpted or shaped antenna beams, such as sector antenna beams, for use in communication networks. Preferred embodiments use passive antenna feed networks, preferably configured as personality modules, which are adapted for corresponding topological and morphological features. Preferred embodiment feed networks may be coupled to linear or curvilinear antenna arrays to provide antenna beams having a desired contour. Using the disclosed systems and methods path loss variance is minimized for improved system capacity and/or signal quality. Moreover, the disclosed systems and methods provide for reduced average transmission power levels further allowing increased capacity and/or signal quality.
