Abstract
- TEM cells that are popular in immunity measurements require high operating power. In this paper, an immunity testing cell using a rectangular loop resonator is proposed. The testing cell is expected to generate high electric field strength at comparatively low power. The resonator comprises a conducting channel plate and a capacitive gap set onto the ground plane. The testing cell has a size of 1/10 wavelength at the testing frequency and therefore is suitable for immunity testing at low frequency. In this study, the electric and magnetic field distribution inside two different types of proposed resonators are analyzed by the FDTD method. Comparison of analytical and experimental results shows a close match. The electric field strength inside the two resonator types is increased by 31.2 and 14.3 dB, respectively, relative to that of the TEM cell of similar size. In the latter type of resonator the electric field deviation inside a square area of 100 mm length is suppressed to 2 dB. Moreover, the resonator covered with a shield case for practical use shows an increase of 11.2 dB in the electric field strength over the level of the similar size TEM cell. The amplitude deviation remains the same as that of the bare resonator. © 2003 Wiley Periodicals, Inc.
