Abstract:

This paper describes a new limited scan antenna technique for electronic scanning arrays. The antenna uses a novel coupling network to achieve fully overlapping subarrays with minimal antenna depth. The coupling network is comprised of contraposed input and output ports interconnected through a one wavelength section of radial waveguide. Antenna and network design principles are discussed in detail. Performance parameters are defined and the major features of the design including very low sidelobe and adaptive nulling capabilities are presented. An experimental demonstration antenna is described, and experimental results for the antenna and coupling network demonstrating the capabilities of the design are presented. Author
