Abstract
A loop antenna array capable of forming a clear boundary of a communication area is provided. The loop antenna array includes three loop antennas, in which a direction of a current flowing through the loop antenna arranged in the middle and a direction of a current flowing through each of the loop antennas arranged on both sides of the loop antenna arranged in the middle are opposite from each other, and the sum of magnetic moments of the three loop antennas is zero.
