A Novel IC-Stripline Cell Design Based on Image Theory

With the purpose of radiation emissions and immunity measurement of large size and high-frequency integrated circuits (ICs), three closed version IC-Stripline cells conforming to the IEC standardswere designed in this paper to expand the uniform field region and the working frequency band of the traditional IC-Stripline cell. In these cells, the long version IC-Stripline cell expands the 3 dB uniform field region of the traditional IC-Stripline cell from 3 × 3 cm to 3 × 8 cm, with the working bandwidth remaining as 6 GHz. The IC-Stripline cell based on image theory further expands the 3 dB uniform field region into two 3 × 8 cm areas with the working bandwidth unchanged. The third cell is a scaled-down IC-Stripline cell based on image theory, which can expand the working bandwidth from 6 GHz to 12 GHz and the total area of the uniform field region is equivalent to that of the traditional IC-Stripline cell.
