Abstract:

In the modern communication world, all are connected with other members of the world through communication devices. The Gigahertz Transverse Electromagnetic (GTEM) cell is a versatile equipment for the measurement of conducting Electromagnetic Compatibility (EMC) with both emission and immunity testing in a free field environment. This paper mostly presents an analysis of GTEM-based testing for multi-frequency applications. The achieved results emphasized the GTEM cell performance to simulate electromagnetic conditions for various electronic devices. All these Electromagnetic emission devices are tested for compatibility prior to trade on the market. In this paper, the immunity and emission tests of different helical antennas and a wideband antenna at various frequencies are tested using a fabricated optimized GTEM cell. The fabricated optimized GTEM cell is validated for multi-frequency immunity, emission test using several helical microstrip and octagonal antennas. The developed antennas at various frequencies, 490 MHz, 800 MHz, and 2.4 GHz, are tested to validate the optimized GTEM cell.
