Abstract
In this paper, an antenna arrangement and a control system that decreases the losses caused by the user of the mobile terminal, is presented. Performance of the system is evaluated with the presence of user hand and index finger. Experimental results prove that two switchable antenna elements are able to increase the total efficiency up to 2.5 dB at 900 MHz.
