- In the conventional model to explain the antenna-phantom interaction for specific absorption rate (SAR) analysis, antenna structures are treated as perfect electric conductors. However, such a model does not suffice to analyze complementary antenna structures, i.e., aperture antennas. In this paper, an antenna-phantom model for aperture antennas is introduced considering the tangential electric field generated by the equivalent magnetic currents as the primary contributor to the peak SAR level. When the out-of-phase tangential electric field of the second-order modes for a slot antenna is achieved, the peak 10-g SAR levels are lower than that is caused by a conventional slot antenna with the first-order mode in the same condition due to destructive superposition. Therefore, the proposed antenna-phantom model is helpful to guide the aperture antenna design for the SAR compliance purposes.
