PROBLEM TO BE SOLVED: To provide a loop antenna array capable of forming a boundary of a linear and clear communication area.SOLUTION: The loop antenna array includes two loop antennas 1 and 2. Electric current runs through the loop antennas 1 and 2 in an opposite direction to each other. That is, when viewed from a direction penetrating through each of the loop antennas 1 and 2, at the timing that a signal terminal of an AC power supply E has plus voltage, clockwise electric current runs through the loop antenna 1 and counter-clockwise electric current runs through the loop antenna 2. At the timing that the signal terminal of the AC power supply E has minus voltage, on the contrary, counter-clockwise electric current runs through the loop antenna 1 and clockwise electric current runs through the loop antenna 2.SELECTED DRAWING: Figure 1 【課題】直線的かつ明瞭な通信エリアの境界を形成できるループアンテナアレイを提供する。【解決手段】ループアンテナアレイは、２つのループアンテナ１、２を備える。ループアンテナ１、２には、互いに逆方向の電流が流れる。つまり、各ループアンテナ１、２を貫通する方向に見て、交流電源Ｅの信号端子がプラス電圧のタイミングでは、ループアンテナ１に時計回りの電流が流れ、ループアンテナ２には反時計回りの電流が流れる。逆に、交流電源Ｅの信号端子がマイナス電圧のタイミングでは、ループアンテナ１に反時計回りの電流が流れ、ループアンテナ２には時計回りの電流が流れる。【選択図】図１
