PICKUP COILS WHICH ARE ASSOCIATED WITH MOBILE TELEPHONES

摘要

The invention relates to pickup coils which are associated with mobile telephones. The inventive coils are characterised in that they can light up luminescent diodes when connected to passive reflectors. Said action is achieved once signal gain has been increased by the passive reflector and the signals that pass through the turns of the reflector induce a sufficient current in the pickup coils in order to illuminate the luminescent diodes. In this way, mobile telephones can be equipped with indicators which have a correct signal level without the need for a connection to be made to any of the turns of the passive reflectors.
