Title:

LOOP ANTENNA ARRAY

Document Type and Number:

WIPO Patent Application WO/2017/126147

Kind Code:

A1

Abstract:

Provided is a loop antenna array capable of forming a clear and rectilinear communication area boundary. The loop antenna array is equipped with two loop antennas 1, 2. The loop antennas 1, 2 have currents flowing therethrough in opposite directions from one another. In other words, when viewing the loop antennas 1, 2 in a direction that passes therethrough, a clockwise current flows through the loop antenna 1 and a counter-clockwise current flows through the loop antenna 2, at times when the voltage from an AC power supply E signal terminal is positive. Conversely, at times when the voltage from the AC power supply E signal terminal is negative, a counter-clockwise current flows through the loop antenna 1, and a clockwise current flows through the loop antenna 2.
