Abstract: A circular phased array system is described which utilizes a lens feed to simplify the problem of commutating the RF distribution system through 360* of steering of the antenna beam. The lens feed consists of a circular parallel plate radial transmission line with a central set of probes and a ring of peripheral probes. The peripheral probes are coupled to an array of radiating elements arranged in a circle. The central set of probes can be energized and phased to produce electromagnetic energy with an amplitude distribution within the parallel-plate line in any given direction. By selective settings of phase and amplitude of the energy coupled to the central set of probes, any sector of the peripheral probes is excited with the proper amplitude distribution necessary to produce a directive antenna pattern with low sidelobes.

Abstract: A circular phased array system is described which utilizes a lens feed to simplify the problem of commutating the RF distribution system through 360* of steering of the antenna beam. The lens feed consists of a circular parallel-plate radial transmission line with a central set of probes and a ring of peripheral probes. The peripheral probes are coupled via switches to an array of radiating elements arranged in a circle. The central set of probes can be energized and phased to produce electromagnetic energy with an amplitude distribution within the parallel-plate line in any given direction. By selective settings of phase and amplitude of the energy coupled to the central set of probes to achieve the proper energy distribution to the peripheral probes and by operating the switches to determine which radiating elements are coupled to the peripheral probes, a desired directive antenna pattern with low side lobes is provided.
