Abstract

La presente invenzione si riferisce ad un apparecchio ricetrasmettitore portatile, in particolare ad un apparecchio telefonico radiomobile, a bassa irradiazione dell'utente comprendente un contenitore ed una antenna applicata a detto contenitore. Dato che tali apparecchi, durante il loro impiego, da parte di un utente, vengono posti vicino al capo dell'utente stesso, una forte quantità di onde elettromagnetiche lo attraversa; in particolare con il continuo incremento della frequenza di trasmissione ed il conseguente decremento delle dimensioni della antenna l'irradiazione del capo dell'utente è e diventerà un problema molto serio.Scopo della presente invenzione è quello di provvedere un apparecchio ricetrasmettitore portatile tale da minimizzare l'irradiazione del suo utente.Applicando l'antenna in posizione opportuna e tale da essere lontana dal capo dell'utente si può ottenere una forte riduzione dell'irradiazione.The present invention relates to a portable transceiver apparatus, in particular to a mobile radio telephone, with low user irradiation comprising a container and an antenna applied to said container. Since such devices, during their use, by a user, are placed near the user's head, a strong quantity of electromagnetic waves passes through it; in particular, with the continuous increase in the transmission frequency and the consequent decrease in the size of the antenna, the irradiation of the user's head is and will become a very serious problem. The object of the present invention is to provide a portable transceiver device such as to minimize the irradiation of its user. By applying the antenna in a suitable position and such as to be far from the user's head, a strong reduction in irradiation can be obtained.
