Abstract:
A directional characteristic acquisition unit  51  rotates a wireless terminal  1  that is a measurement target using a terminal holding rotation mechanism  30  centering around a standard point O, measures a field intensity Pr of a radio wave received by the measurement antenna  21  at each rotation angle (ϕ, θ) to calculate a virtual directional characteristic of a terminal antenna  1 a  in the wireless terminal  1 . An error information output unit  60  calculates a reception angle error (ϕ′, θ′), a propagation loss error E1, and a gain error E2 that occur in accordance with rotation of the wireless terminal  1 , and corrects a virtual directional characteristic using these errors, using a correction unit  70 , to calculate a directional characteristic Hc in a case where it is assumed that the terminal antenna  1 a  of the wireless terminal  1  is rotated at the position of the standard point O.

Claim (Index 3):
The wireless terminal antenna directional characteristic measurement system according to  claim 1 ,\n wherein the error information output unit includes\n a reception angle error storage unit that stores, in a state where a plurality of candidate positions capable of becoming the position of the terminal antenna in a case where the wireless terminal that is the measurement target candidate is disposed at the standard position are set in the measurement space, the reception angle error at each rotation angle of the wireless terminal that is calculated in advance with respect to each of the plurality of candidate positions, \n a propagation loss error storage unit that stores the propagation loss error in the free space at each rotation angle of the wireless terminal that is calculated in advance, with respect to each of the plurality of candidate positions, \n a gain error storage unit that stores the gain error of the measurement antenna at each rotation angle of the wireless terminal that is calculated in advance using the reception angle error stored in the reception angle error storage unit and the directional characteristic of the measurement antenna with respect to each of the plurality of candidate positions, and \n an error information read-out unit that reads out the reception angle error, the propagation loss error, and the gain error at each rotation angle of the wireless terminal that are stored in advance in the reception angle error storage unit, the propagation loss error storage unit, and the gain error storage unit with respect to a candidate position corresponding to the position input through the antenna position input unit among the plurality of candidate positions, and provides the result to the correction unit.
