Title:
INSTRUMENT AND METHOD FOR MEASURING ANTENNA
Document Type and Number:
Japanese Patent JP3660181
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten the time necessary for measurement, and to make it unnecessary to use an extremely high-precision driver in case of a millimeter wave or submillimeter wave and reduce the manufacturing cost by making it unnecessary to measure a large number of two-dimensional electric field distributions, when measurement of two-dimensional electric field distribution is required as in neighboring field measurement, and doing without a measuring distance varying apparatus which requires high driving precision at some measuring wavelength when measuring distance is varied.
SOLUTION: The amplitude distribution and the phase distribution of a two-dimensional electric field are field-converted at an imaginary wave source position of an unnecessary wave, and unnecessary wave components contained in the amplitude distribution and the phase distribution of the two-dimensional electric field are computed, and the unnecessary wave components are removed from the amplitude distribution and the phase distribution of the two-dimensional electric field.
