The temperature test apparatus includes a test antenna for measuring transmission and reception characteristics of a DUT, an anechoic box formed by a metal housing having an internal space, a heat insulating housing, a temperature control device that controls the temperature of a spatial region, and a measurement device that measures the transmission and reception characteristics of the DUT. The temperature control device and the heat insulating housing are connected to each other by a pipethrough which a gas for controlling the temperature of the spatial region passes and that goes through the metal housing. A portionA of the pipe from the metal housing to a predetermined position of the internal space is made of metal. A metal net portionthat blocks a pipelineAe of a portion of the pipeis provided.

Temperature test apparatus and temperature test method

A temperature test apparatusincludes a test antennaconfigured to transmit or receive a radio signal to or from the antennasin order to measure reception characteristics or transmission characteristics of the DUT, a heat-insulating housingmade of heat-insulating material surrounding a space regionincluding a quiet zone QZ, and a measuring deviceconfigured to measure the transmission characteristics or the reception characteristics of the DUT. The heat-insulating housinghas a flat plate shaped partin a region through which radio waves of a radio signal transmitted from the test antennapasses before entering the quiet zone QZ. The flat plate shaped partis perpendicular to the traveling direction of the radio waves of the radio signal entering the quiet zone QZ.
