Abstract
A wireless passive field strength probe includes monopole antennas; a detection module; a micro processing device; a wireless transmission module and an antenna module, wherein the wireless transmission module is connected to the micro processing device and the antenna module; a frequency of the antenna module is different from a frequency of the field to be measured, and is not a harmonic of the frequency of the field to be measured; and a power module connected to the detection module or the antenna module. The wireless passive field strength probe of the present invention transmits the vector electric field, the probe serial numbers and the coordinate signals of the probe in real time through the wireless transmission module, and provides the power supply to the communication module through detecting or receiving microwave signals through the antenna, thereby avoiding inaccurate wireless measurement.
