| Abstract(in English) | This report describes a method to improve resolution of an E-field probe with signal processing technique without hardware modification. In order to study the emission to from PCB, for example, it is useful to obtain near field distribution. Existing method has been obtained E-field strength distribution by scanning an E-field probe and multiplying its antenna factor by the output voltage. However, the method has following disadvantage: 1)the corredation between near E/M field distribution and the probe output voltage has not been proved, 2)there is not enough resolution for the latest small schematic. In this report, we propose a new method, which makes it possible to reduct those problems by using E-probe's spatial responses. Experimental results show that proposed method can separate two null points, which can not separated with conventional method. |
