ABSTRACT:
A rotary coupled transmission line cell is disclosed which generates standard electromagnetic waves needed for measuring the electromagnetic wave susceptibility (EMS), for measuring the electromagnetic wave interference (EMI) and for correcting the probe. In the present invention, two internal conductors are used to have a 4-port structure, and therefore, the generation of the circulation transmission waves are inhibited during the generation of the standard waves having arbitrary impedances. Therefore, accurate standard waves can be generated, and adjustments of arbitrary polarizations and arbitrary irradiating directions are made possible. Further, when an odd mode power supply is carried out to the internal conductors, the standard electromagnetic waves having a uniformity as high as 3 times that of the conventional ones can be generated. Further, an inverted L shaped test object supporting plate is installed, so that the polarization can be carried out with a greater adjustment width.
