- Abstract:
- Use and application of the TEM-cell has been described. The cell can be used for calibrating small antennas, for immunity and emission testing. It has frequency response up to the first cut-off frequency, which in our case is 485 MHz, but can still have useful areas at higher frequencies (900 MHz). Laboratory experiments as well as commercial testing of the equipment such as cellular phone, IC boards, or small electronic devices up to 5 cm in height are possible. It provides homogenous electromagnetic fields with TEM (transversal electromagnetic mode) distribution, similar to the free space. It has a shield to prevent radiation from the outside, which would interfere with the measurement. Electric and magnetic field inside the cell can be accurately predicted using numerical methods. The measurements of TEM-cell, designed and made at the University of Zagreb, Croatia, of return loss and standing voltage ratio were done. Measurement setup and the method have been explained.
