PURPOSE: To shorten a measurement time and to improve measurement precision by providing plural probes so as to obtain data at the same time in a neighborhood antenna measuring device, in which a distanced field radiation pattern is found by measuring the neighborhood of the antenna and processing the data.

CONSTITUTION: Plural probes 1a, 1b are arranged toward an antenna to be tested 6, which rotates around an appointed shaft on a rotary table 7, and the electric waves detected by these plural probes 1a, 1b are received by receivers 3a, 3b provided corresponding to the probes 1a, 1b respectively or by one of the receivers via a switch switching plural probes 1a, 1b, and subsequently, a receiving signal is processed by a data processing device 5. For the measurement is carried out by plural probes at the same time, the measurement time is shortened and a measurement error factor due to a change over time in the measuring device can be reduced.
