Abstract

In this paper, an ultra-wideband standard transducer based on microstrip line is developed for the accurate measurement and metrology of UWB-SP. The transducer consists of a section of microstrip line and a section of coaxial line connected to microstrip line via an SMA connector. The beginning end of the transducer is chosen to receive the excitation signal, to expand the effective time window. Simulated results show that the waveform recovered by the transducer is almost coincident with the excited electric field waveform within the effective time window, and the upper frequency of the bandwidth is up to 3.5 GHz. The measured results show that the transducer can recover the waveform of the incident electric field very well, the sensitivity and time window can be calibrated readily and accurately by and the vector network analyzer as well as the UWB TEM cell. The experimental results are in agreement with the results from theoretical results and simulated results.
