US Patent 10177823 Antenna control apparatus, antenna control program, and antenna control system

Provided is an antenna control technique for forming the boundary of a communication area at a desired location. An antenna parameter control apparatus 2 calculates an antenna parameter in a case of feeding electric currents with an equal intensity in mutually reverse directions to two antennas 1A, 1B which generate a magnetic field. The antenna parameter control apparatus 2 includes an input parameter acquisition unit 21 that acquires input parameters for calculating the antenna parameter; and a parameter calculation unit 22 that calculates an inter-center distance d between the antennas 1A, 1B as the antenna parameter based on the input parameters.
