Reconfigurable flat dielectric stack lens for azimuth beamwidth tuning

Abstract

A C-Band array is formed of beamwidth-controlled radiator column. Each beamwidth-controlled radiator columns comprises a plurality of radiators; and a reconfigurable lens disposed over the plurality of radiators, wherein the reconfigurable lens has a bottom layer that has a plurality of bottom layer holes, and a middle layer that has two middle layer sections that are separated along an azimuth axis by a gap, and wherein the reconfigurable lens has one or more beamwidth control sliders that are configurable to translate along a vertical axis, wherein the reconfigurable lens is formed of a dielectric material. By translating the beamwidth control sliders, one can adjust the azimuth beamwidth of the radiators. This may be done remotely after the antenna is deployed, to adjust for optimal beamwidth in the presence of interferers.
