Research on Response of Log-Periodic Antenna (LPDA) to Square Wave Pulse in GTEM Cell

Abstract:

In order to study the response of the log-periodic antenna (LPDA) to a square wave pulse, it has been irradiated in a square wave pulse using GTEM cell and high-frequency noise generator. And the waveform and frequency spectrum signals are measured. Before the test, the pulse field in GTEM cell has been calibrated. The results showed that field intensity in it changes with the voltage varies linearly strictly at the same point, but with the height of core plate increases, the field intensity decays exponentially but not strictly linear attenuation relationships. Experiment results show that it is feasible to acquire antenna’ square wave pulse response using GTEM cell, and the results is instructive for the analysis of the impulse response and protection for a log-periodic antenna.
