不同的天线配置上的数值和物理幻影的影响进行了评估。输入响应，辐射模式和效率被认为是在幻影的存在。为了验证体模作为人体组织的替代品，将这些效应与由于接近人体而经历的效应进行比较。演示了由于体模对贴片天线的失谐效应，并显示与人体效应相匹配。在体模上和体模外测量环形天线的辐射模式。发现体模的存在使环形天线的效率降低了88%。
The effects of a numerical and a physical phantom on different antenna configurations are evaluated. Input response, radiation patterns and efficiency are considered in the presence of the phantoms. In order to validate the phantoms as a substitute for human tissue, these effects are compared to those experienced due to the proximity of the human body. The detuning effects on a patch antenna due to the phantom were demonstrated and shown to match the effects of the human body. The radiation pattern of a loop antenna was measured on and off the phantom. The presence of the phantom was found to reduce the efficiency of the loop antenna by 88%.
