Abstract (en)
The present invention relates to a portable transceiver apparatus, in particular radiomobile telephone set, with low irradiation of the user including a handset and an antenna mounted on said handset. Since said apparatuses (AC) during use by a user, are placed near the user's head (U), a great amount of electromagnetic waves pass through it; in particular with the continuous increase in the frequency used and the consequent decrease in the antenna's dimension, the irradiation of the user's head is and will become a serious problem. The aim of the present invention is to provide a portable transceiver apparatus such as to minimize the irradiation of its user. By placing the antenna in a suitable position such as to be far away from the user's head, a greatly reduced irradiation can be obtained. <IMAGE>
