LOOP ANTENNA ARRAY AND LOOP ANTENNA ARRAY GROUP

摘要

Provided is a loop antenna array that can easily create a magnetic field distribution which enables the boundary of a communication area to be clearly set. 2 n loop antennae are provided adjacently to one another, where n is a natural number. The directions of currents in adjacent ones of the loop antennae are opposite to each other. For example, in a loop antenna array 1, two loop antennae, loop antenna 11 and loop antenna 12, are disposed adjacently to each other on an insulator substrate 10. First feed points 13a, 13b energize the loop antenna 11, and second feed points 14a, 14b energize the loop antenna 12.
