摘要

A new method to decrease the effect of the hand and head on the operation of mobile terminal antennas at the 900 MHz frequency band is introduced. The proposed structure consists of two antenna elements. Depending on the use position, the better-performing antenna element is selected and the other is acting as a shield. It is shown by simulations that the proposed structure can improve the total efficiency with the hand by up to 4.8 dB and decrease the maximum specific absorption rate in the head by 30-44% compared to the traditional single element structure.
