Study of surface wave antenna loaded with artificial magnetic conductor surfaces

Abstract

In this paper, a new metamaterial-inspired high frequency surface wave antenna is designed. An artificial magnetic conductor surface is introduced into the near field region of a vertical meander monopole antenna to improve its electromagnetics performances, where a split ring resonator-cell is selected as an artificial magnetic conductor. The return loss, the radiation pattern, the electric field distribution and efficiency are evaluated through the finite element method (FEM simulations). The designed antenna has advantages of low cost, small size, and light weight.
