It is demonstrated how the realized efficiency of a mobile phone antenna, placed beside a head-phantom, can be increased approximately 1 dB by adding a parasitic radiator on the front side of the ground plane. The effect of the parasitic radiator is a cancellation of a part of the near field impinging on the head. This reduces the amount of power dissipated in the head and hence, the realized efficiency is increased.
