Abstract:
1. A shaped-beam antenna having a multi-layered conductive element array structure surrounded by a dielectric ring, comprising: a planar excitation element having a radiation structure according to a required polarization; a multi-layered conductive element array disposed on the planer excitation element, wherein the multi-layered conductive element array is formed by layering conductive elements at an arbitrary interval; and a dielectric ring surrounding the multi-layered conductive element array at a predetermined separation distance therefrom wherein the flat-topped beam pattern is generated by adjusting design parameters of the dielectric ring, wherein the design parameters of the dielectric ring include a dielectric constant, a radius, a height, and a thickness of the dielectric ring, and wherein a radius of the dielectric ring is between 1.4 and 1.6λ
