Abstract

A mobile 'phone is provided with an antenna 2 which is arranged to point away from the user's head 4, i.e. it does not lie in the plane of the 'phone, so as to minimize the emission of radiated energy 3 in the direction of the user's head. Alternatively, the antenna may swivel or extend to point away from the user's head and the extension or swivelling of the antenna may happen automatically when the 'phone is opened for use or when the answer button is pressed. Preferably a radiation shield is incorporated into the 'phone, so as to be located between the antenna and the user's head when the 'phone is used, to further reduce the radiation emission towards the user.

Description

2350482 MOBIALE PHONE ANTENNA ARRANGEMENT The invention relates to the
design of the antenna in mobile phones.
There is concern over the safety of pre-donged mobile phc,ne use. In particular to electromagnetic radiation emitted by the antenna of the said mobile phone damaging the user's head or brain whilst this is transmitting.
According to the present invention, the ante,,,,ia position and orientation with respect to the mobile phone is arranged se) as to minimi2e the radiated energy emitted in the direction of the user's head. Thus i-,,,tii-,.Lmizing the DOSSIble risk that s'd radiation could be harmful. The - al &.aiated energy distribution of an antenna of the type comiTionly used in mobile phones is at a maximum perpendicular to the antenna and at a minimum in the rjla..-. the antenna.
The invention envisages an antenna which operates in a position perpendicular to the mobile phone, thus minimizing the radiated energy in tlle direction of the user's head. The antenna can for convenience be made to swivel or extend, in a direction pointing away from the ear. perpendicular to the phone when this is in use, and retract or swivel back so as not to be cumbersome when not in use. Such swivelling or extending action can, if desired, be made to happen automatically when the phone is opened for use, or for example an answer button is pressed.
As an additional feature, it is envisaged that an, integral shield can be incorporated into the phone, positioned between the antenna in it's operating position and the user's head. Be;zause the antenna protrudes to the rear. such a shield can be incorporated into the body of the phone.
1 2 A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which;Figure 1 shows the present conventional arrangement Figure 2 shows the new safer antenna arrangement Referring to fig 1 and fig 2, 1 represents the mobile phone, 2 the antenna, 3 the electromagnetic radiation, 4 the user's ear.
Although the drawings show the mobile phone viewed edge on as being vertical, in practical terms the user actually holds the phone at an angle. Transmission by the antenna in fig 2 is thus almost as good as transmission by the conventional arrangement of the antenna in fig 1. However the radlated energy to the head is significantly less with the arra-ngement of fig 2.

Claims (1)

  1. 3 CLAIMS
    1 A mobile phone antenna arrangement in which the position and orientation of the antenna is arranged so as to minimize the emission of radiated energy in the direction of the user's head, such arrangement being characterized by the antenna not being positioned in the plane of the phone but swivelling or extending to point away from the user's head.
    2 A mobile phone incorporating an antenna arrangement as claimed in claim 1.
    3 A mobile phone incorporating an antenna arrangement as in claimed in claim 1 that in addition has a radiation shield incorporated so as to further reduce electromagnetic radiation in the direction of the user's head.
