| Abstract: | In this paper, the antenna-radome system in millimeter wave band is analyzed by the aperture integration-surface integration (AI-SI) method. When the electromagnetic wave passes through the radome, the transmission coefficient is determined by the transmission line analogy. However, the conventional transmission coefficient always ignores the phase factor of the lateral transmission in the dielectric. In the present work, the modified transmission coefficient is proposed and verified by both the theoretical derivation and the experimental measurement. The measured results of the antenna-radome systems at W-band show that the modified transmission coefficient is more accurate than the conventional one in the antenna-radome analysis. |
