Abstract

The influence of electromagnetic waves on living things has been of great concern in recent years. Traditionally, electromagnetic radiation device for cell experiments has a narrow frequency range and small radiation space. In this paper, a DC to 5.2-GHz rectangular transverse electromagnetic (TEM) device for cell experiments is proposed. The novelty of this research lies in the wide frequency range and sufficient radiation space under the condition of ensuring the transmission performance. The rectangular device is composed of a closed rectangular coaxial transmission line, tapered transition regions, inner plate structure, and dielectric supports. After simulation, optimization, and measurement, both the results of the simulated and measured studies indicate that reflection coefficient S11 is below −10 dB and transmission coefficient S21 is nearly 0 dB. It is demonstrated that the device has a good transmission performance from DC to 5.2 GHz, which meets the requirement for wideband cell radiation experiments. The proposed rectangular device is a good candidate for cell radiation experiment device.
