Abstract
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.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, two loop antennae are disposed adjacently to each other on an insulator substrate. First feed points energize one loop antenna and second feed points energize the other loop antenna.
