| dc.description.abstract | In this thesis, a passive electric field sensor based on a substrate-integrated waveguide (SIW) resonator is designed, fabricated, and evaluated in the measurement of electric field of high voltage produced by two parallel plates. The proposed sensor is potentially applicable to measure the electric field of the high voltage apparatus remotely. When exposed to an external electric field, the resonance frequency of the SIW resonator-based sensor changes due to the variation of the capacitance of diode varactors that are mounted on the sensor. The capacitance of the varactor diode is a function of the voltage induced in its terminals. The sensor is designed to work in the industrial, scientific and medical (ISM) radio frequency band and demonstrates a high loaded quality factor of more than 200. An interrogation system has been developed that is capable of measuring the time-varying resonance frequency of the proposed sensor and deriving the waveform of the external electric field. The interrogation system transmits pulses of radio frequency (RF) signals to the sensor and the sensor re-emits the decaying ring back signals. The recorded ring back signals are downconverted and analyzed to derive the resonance frequency of the sensor. | en_US |
