摘要：An electromagnetic compatibility (EMC) test cell has an electromagnetically screening enclosure which is rectangular in cross- ction with a length and first and cond pairs of oppod side walls. A first antenna array compris a first array of conductors extending lengthwi in the enclosure distributed at positions between the first pair of side walls to produce, when energized in TEM-mode, an electric field in a first test region of the enclosure which is predominantly polarized in a direction parallel to the first pair of side walls. Second and third antenna arrays comprising respective cond and third arrays of conductors extend lengthwi in the enclosure on opposite sides of the first test region. The conductors of each of the cond and third arrays are distributed at positions between the cond pair of side walls to produce, when energized in balanced TEM-mode, an electric field in a cond test region between the cond and third arrays which is predominantly polarized in a direction parallel to the cond pair of side walls. Feeds connect to a feed end of the conductors of each array to energize the arrays, and impedance matched termination of the conductors of the arrays is provided. The resulting test cell can be energized either vertically or horizontally and provides a relatively large area of relatively uniform field.
