Abstract
An omni directional coverage multibeam antenna composed of facets, or antenna modules, that make up a regular polygon of n sides inscribed in a circle of radius r which defines an adjustable composite conical surface. The disclosed antenna modules are independent antenna arrays creating an independent beam. One advantage of such a system is that the radiated wave front associated with such antenna modules is always substantially broadside to the array resulting in limited scan loss effects. Furthermore, the independence of the disclosed antenna modules is important as it allows each module's beam to be either electrically or mechanically steered to affect elevation or azimuthal beam control. Additionally, by employing trapezoidal shaped antenna modules, a minimum radome diameter is achieved that covers this antenna system.
