Abstract
In one scenario, a pillbox array is provided. The pillbox array includes a feed network unit that receives an input wave. The feed network unit includes feed branches for splitting and transmitting the input wave, pillbox reflectors that collimate the input wave, and radiating waveguides for radiating the collimated input wave. The pillbox array further includes a load plate mounted on the feed network unit, where the load plate has load elements placed between the radiating waveguides. This pillbox array also includes a polarizer plate that is mounted on the load plate and the feed network unit. The polarizer plate includes polarizers arranged such that when the polarizer plate is laterally shifted to a first side of the radiating waveguides, a first circular polarization occurs, and when the polarizer plate is laterally shifted to a second side of the radiating waveguides, a second circular polarization occurs.
