Sažetak
Use and application of the GTEM-cell, which is a transmission structure based on a TEM-cell approach, has been described. The cell can be used for calibrating small antennas, for immunity and emission testing. Its broadband frequency response from DC up to app. 20 GHz enables laboratory experiments as well as commercial testing of the equipment such as cellular phone, IC boards, or small electronic devices up to 0.2m x 0.2m in size. 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 our measurement. Electric and magnetic field inside the cell can be accurately predicted using numerical methods. GTEM-cell designed and made at the University of Zagreb, Croatia was presented in this paper as well as the measurements in frequency domain ; return loss and standing voltage ratio. Measurement setup and the method have been explained.
