Abstract

A broadband solar cell antenna includes a first solar cell layer, a first dielectric supporting layer, an antenna layer, a second dielectric supporting layer, and a second solar cell layer sequentially from top to bottom. The first and second solar cell layers are structurally identical; the first and second dielectric supporting layers are structurally identical; a monopole is a metal base copper-clad laminate in a shovel-shaped structure; a trumpet-shaped grounded coplanar waveguide (GCPW) feeding line is used; and a solar cell array forms a meta-surface structure. The broadband solar cell antenna has the features of broadband, miniaturization and low profile. The antenna layer is provided between the two solar cell layers. Solar cells on an upper surface and a back surface of the antenna can collect light in different angles. The antenna has desired radiation performance and can function as both an antenna and a solar cell.
