Abstract
Provided is an antenna control technique for forming the boundary of a communication area at a desired location. An antenna parameter control apparatuscalculates an antenna parameter in a case of feeding electric currents with an equal intensity in mutually reverse directions to two antennasA,B which generate a magnetic field. The antenna parameter control apparatusincludes an input parameter acquisition unitthat acquires input parameters for calculating the antenna parameter; and a parameter calculation unitthat calculates an inter-center distance d between the antennasA,B as the antenna parameter based on the input parameters.
