Description
FIELD OF THE INVENTION
The present invention relates to a portable phone, cellular or otherwise, provided with a separate antenna.
The last ten years have seen a phenomenal increase in the use of portable phones and wireless telecommunication devices with the growing Io popularity of wireless communications. There is however concern that the regular use of such wireless communication devices, especially in the case of cellular phones, may cause physiological damage to the user as the brain is repetitively exposed to electromagnetic radiation of relatively high power. It has been more particularly proposed that such a frequent use of wireless is phones may be a factor in the emergence of brain cancer.
The is therefore a need for a device that possesses all the advantages of wireless phones while avoiding the exposure of the brain to harmful electromagnetic radiation.
2o SUMMARY OF THE INVENTION
The present invention provides a portable communication device including a phone receiver and a long range main antenna, for example of the type used in any regular cellular phone. Means to attach the main antenna to a part of the body of the user removed from his head are also provided.
2s Advantageously, the main antenna may be affixed to a belt clip that is removably attached to the user's belt, such as belt clips already in use to carry the phone receiver itself. The receiver is provided with a secondary, omnidirectional antenna for producing short range radio waves. This type of radiation is much less damageable for the body as it not as energetic as higher 3o frequency radiation. The main antenna may then be provided with means to

2 convert the radio emission from the secondary antenna into higher energy waves adapted to be transmitted by the main antenna for long range communications.
In a preferred embodiment of the invention, the belt clip includes a s directional antenna, projecting away from the body of the user. The belt clip also includes power means, such as batteries, for powering the antenna and communicating with the cell site. The belt clip also includes a low-power emitter/receiver for communicating with the portable phone itself. Preferably, the range of frequencies for communication between the portable phone and to the belt clip is in the range of 900 MHz, and is of sufficiently low power to not require regulatory approval.
Consequently, the portable phone (or handset? can be made very small and of low power consumption, since it only requires to communicate with the belt clip. Thus, battery life if considerably increased.
Is The belt clip, or any other appropriate casing which will direct the power away from the body of the user, can be equipped to be placed on a stationary base (for example in the office or at the home), for recharging the battery, all the while permitting use of the portable phone. It is also important to note that the purpose of the invention is essentially to separate the antenna 2o for a portable phone from the handset itself, to reduce any long-term health risk associated with use of a portable phone. Consequently, the invention can be embodied in a directional antenna integrated into a belt clip, so that the handset communicates with the belt clip through low-power transmissions, but variations on the theme are possible.
2s It should be understood however that the present invention is not limited to phones, but is applicable to any wireless communication device.
The accompanying drawing show a preferred embodiment of the invention, where Tx and Rx mean transmit and receive, respectively, and H.S.
means handset.
