Electrically-tunable circularly-polarized composite multi-mode reconfigurable orbital angular momentum antenna

Abstract

The invention discloses an electrically-tunable circularly-polarized composite multi-mode reconfigurable orbital angular momentum antenna which comprises a first dielectric substrate and a second dielectric substrate which are sequentially arranged from bottom to top. A third dielectric substrate is arranged on the second dielectric substrate, and an air layer is arranged between the third dielectric substrate and the second dielectric substrate. A metal feed network is printed on the lower surface of the first dielectric substrate, a metal floor with the same shape and size as the first dielectric substrate is printed on the upper surface of the first dielectric substrate, and four metal radiation sheets are printed on the upper surface of the second dielectric substrate. The third dielectric substrate comprises four circular third dielectric substrate units which are arranged on the same plane and have the same shape and size; circular metal coupling patches with the same radius areprinted on the lower surfaces of the third dielectric substrate units respectively; and four feed probe units are also provided. The antenna can further overcome the problems of single performance andcomplex array feed network structure during reconstruction.
