1. A wireless passive field strength probe placed in a field to be measured, comprising:
three monopole antennas respectively arranged in X/Y/Z axis directions for sensing a field strength to be measured;
a detection module for converting an electric field received by the monopole antennas into a voltage;
a micro processing device for signal acquisition and processing;
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.
