Abstract

A portable telephone aerial radiation shield located along the exterior of the antenna to protect the user from emanating radiation. The shield is made of a material capable of blocking, absorbing or reflecting radiation and the material may be made of different compounds and thicknesses to optimally protect the user. The shield may be attached or adhered to the exterior of the aerial or an integral part of the aerial. Alternatively the shield may be part of a casing over the phone.

Description

2350725 MOBILE PHONE AERIAL RADIATION SHIELD Mobile phones are becoming

more popular every day, in fact they are here to stay, with the manufactures aiming at 40% usage in the U.K. the same as Finland the home of Nokia, who now produce world wide in the region of five million phones per month. As more people are using mobile phones, there is a pattern of medical problems emerging that are associated with the use of the mobile phone. The main problem appears to be the radiation that is emitted directly into the brain when the phone is in use. (transmitting and receiving).

On the market at the moment are a few devices, which help to protect the user from the radiation, these are jackets which fit over the phone and are usually lined with a lead type product which will absorb or reflect the radiation. The problem here is that the aerial cannot be covered by the jacket as the phone will not work, but the aerial is the main source of the radiation.

The present invention aims to overcome the drawbacks of the conventional aerial.

Normally the aerial on a mobile phone is on the top of the phone and on most new phones the aerial is usually about 2-3 cm long and 1 cm wide.

Radiation, microwaves, and radio waves, which are, produced when a mobile phone is transmitting and receiving usually travel in straight lines (Fig 1). So when a mobile phone is in use it is placed against the ear, which means the aerial is in direct line with the users brain and with some models this means the aerial is no more than 2 cm from the skull of the user.

The present invention aims to overcome or reduce the direct penetration of radiation into the brain, by placing a shield along the length of the aerial, as the radiation comes from the core of the aerial (Fig 28).

The construction of the aerial usually has piece of wire in the centre that runs the length of the aerial and is enclosed in plastic.

It is important for this invention that the'shield runs the length of the aerial and is wide enough to blank out a segment of the radiation (Fig 2/3) when the phone is in use.

It is important for this invention that the shield is placed directly between the core of the aerial and the brain of the user (Fig2/3).

a When the mobile phone is in use (transmitting and receiving) radiation is emitted from the aerial so if a shield in the form of a strip of lead or something with the same ability as lead to absorb, or reflect radiation, is placed along the length of the aerial, between the core of the aerial and the brain of the user, direct radiation into the brain of the user is avoided, or reduced.

If different thickness of shield are used and matched to the power of the mobile phone it is possible to reduce the radiation the user receives to their brain.

If different compounds are used for the shield and matched to the power of the phone it is possible to reduce the radiation the user receives to their brain.

In trials on four different makes of mobile phones, in four different locations on the ability to make and receive calls with the shield fitted, no problems were experienced at all.
