A Σ-Δ directional antenna array for electromagnetic(EM) energy harvesting is proposed in this paper. By applying the Σ-Δdirectional antenna array with the 180-degree hybrid circuit, it is possible to convert more electric power from the EM wave. The results of the consideration by the indoor environment using the ray tracing method are reported that the received electric power by the Σ-Δ directional antenna array is improved more than the single directivity antenna.
