MEASURING AND REDESIGNING OF TEM CELLS FOR FREQUENCY BANDWIDTH WIDENING

摘要

Now, the TEM cells are constructed according to requests of IEC 1000-4-3: 1995 and CISPR 20: 1996, having a frequency bandwidth till 150 MHz. This frequency bandwidth is used for electromagnetic field immunity test. The paper presents a new way of stripline design for getting a frequency bandwidth extension till 1000 MHz. In this manner one could realise the electromagnetic immunity test by sweeping all range of frequency from minimal requested frequency to 1000 MHz by using a constant level of line input voltage.
