Abstract
An antenna apparatus is configured to include: a DUT scan mechanism that executes total spherical scanning on a DUT having an antenna in an internal space of an OTA chamber around a reference point; a plurality of antennas disposed at a distance within a near field measurement range from the reference point; and signal analysis devices that respectively perform a near field measurement process related to total radiated power (TRP) based on reception signals of the antennas which receive radio signals in a spurious frequency bandwidth radiated from the antenna transmitting and receiving radio signals in a specified frequency bandwidth, during execution of the total spherical scanning.
