A method for measuring a power radiated solution, coupler for measuring a radiated power, and apparatus for measuring a power radiated

摘要

A method for measuring a radiation power, characterized in that it comprises the following steps:Arrangement of a device (dut) (1), which is capable of radiating scheme that uses radio wave, in such a manner that the radiating center of the scheme that uses radio wave of the dut (1) substantially with the vicinity of a first focal point (f1) of an enclosed space (12), the by means of a metallic wall surface (11) of an ellipsoid is limited, by rotation of an ellipse which through the first focal point (f1) and a second focal point (f2) extending axis is obtained; andReflecting the scheme that uses radio wave emitted by the dut to the wall surface and receiving the scheme that uses radio wave by means of a in the vicinity of the second focal point (f2) receiving antenna (15) is arranged, in order in this way at the measuring end of the receiving antenna the entire beam power of the dut on the basis of the output signal to measure of the receiving antenna,the dut or / and the receiving antenna along the through the first and the second focal point extending axis..
