摘要：
This letter investigates the effect of the human head on the accuracy and depth of an adaptive nulling when the antenna array is implemented on a handset at 5.0-GHz band. Our numerical results show that the MUSIC spectrum obtained by the linear dipole array is largely affected by the coupling between the antenna and the head model. In particular, this effect is dependent on the separation between the array and the head. In order to suppress this effect, a metallic plate is inserted between the array and the head. The effectiveness of this proposal is demonstrated numerically.
