| Abstract: | In order to acquire the transient response of a log-periodic antenna （LPGA）,its inducted time signal under a square wave pulse was measured and analyzed using the GTEM cells and the full-wave analysis simulator CST.To calibrate GTEM cells,the distribution of electric field in it was measured using an ultra-wide band test system.The result reveals the relationship between the field intensity E（t）in GTEM cells and the input V（t）,the height h.Then,the test system using GTEM cells was established to get the transient signal of LPGA.The response signal when it is illuminated by square wave plane of different orientation is obtained.The last,a 3D model of this antenna was established using simulator CST.The simulation analysis shows that the peak voltage of the transient signal is able to be calculated by the equivalent circuit with open-circuit voltage source. |
