A recycled energy method using a directional antenna is proposed about the electromagnetic wave energy harvesting to convert electric power from electromagnetic waves. It is possible to convert much electric power by applying the dual directional antenna using the180-degree hybrid circuit to the electromagnetic wave harvesting. In this paper, the dual directional microstrip patch antenna applying the rat-race circuit with Σ and Δ characteristics is designed and it is reported that the proposed antenna has the dual directional radiation pattern of the single directivity and the monopole directivity.
