Abstract

The effect of the human head on the accuracy and depth of adaptive ing has been investigated. The frequency band considered was 5.0 GHz, which would be the most promising for the 4G mobile communications. Our numerical investigation shows that the MUSIC spectrum obtained by the linear dipole array is largely affected by the antenna-head coupling. In particular, this effect is dependent on the separation between the array and the head. In order to suppress it, a metallic plate was inserted between the array and the head. The effectiveness of this idea was demonstrated numerically.
