Abstract

An electromagnetic signal measurement system is disclosed, which utilizes the low-interference measurement technique of electromagnetic field combined with an automatic positioning mechanism. The electromagnetic signal measurement system is especially suitable for use in an open space; for example, the field measurement of RFID readers and RFID tags. The electromagnetic signal measurement system provides the features of eliminating the issue of disturbed antenna field measured by a conventional antenna measurement and measuring the antenna field automatically. One embodiment of the present invention contains a source to be determined, a first platform carrying the source, an optic electric field sensor sensing a signal from the source and a second platform carrying the optic electric field sensor.
