The radio wave radiated from the DUT and reflected from the wall surface is received by a receiving antenna arranged in the neighborhood a second focal point thereby to measure the total radiated power of the DUT from the output signal of the receiving antenna. One of the DUT and the receiving antenna is moved along the axis passing through the first and second focal points, and based on the measurement value maximizing the output signal power of the receiving antenna, calculating the total radiated power of the DUT.

In the linearly polarized antenna, generation of a surface wave is suppressed by the cavity and the conducting rim, and the antenna can be set to the desired radiation characteristic. Additionally, a frequency characteristic of an antenna gain can have a steep decline (notch) in an RR radio-wave emission prohibited band by utilizing a resonance phenomenon of the cavity. Therefore, the linearly polarized antenna is effective in decreasing radio wave interference with EESS or radio astronomy service.

摘要： Provided is a technique capable of accurately calculating the radiation power of an object to be measured using a spheroidal coupler even when there is a non-negligible loss in a measurement system.A phase rotating unit including a variable phase shifter, a two-branch circuit, and a reflective element that is connected to one of the branched outputs of the two-branch circuit is inserted between a receiving antenna and a power measuring device. The maximum value and the minimum value of power measured by a power measuring device when the variable phase shifter changes a phase are calculated. An output reflection coefficient of a coupler is calculated from the ratio of the maximum value to the minimum value, and an input reflection coefficient of an object to be measured which is approximate to the output reflection coefficient is estimated. In addition, an input reflection coefficient of a reference antenna which is used instead of the object to be measured is estimated in the same way. The total radiated power of the object to be measured is calculated on the basis of the estimated input reflection coefficients and the reception power when the power measuring device directly measures the output of the receiving antenna.
