Measurements of the effectiveness of antenna screens for protection of the head from mobile phone radiation

Measurements have been taken of the electromagnetic field distribution around a mobile phone which was transmitting CW at 890 MHz. The measurements were taken using a mobile phone with a short monopole antenna and were then repeated with a reflector (that is supposed to protect the head from radiation) interposed between the head and the radiating antenna. Measurements of field magnitude and phase were made so that animations of the propagating fields could be observed. Comparisons of the field distributions and conclusions regarding the effectiveness of the reflector could then be made.
