发明名称 Method and device for local elimination or restriction of a radio-frequency radiation field
摘要 The invention relates to a method and apparatus for locally eliminating or reducing a radio-frequency radiation field, particularly in telephones from the antenna in the direction of a user, when using a dipole antenna consisting of at least two antenna elements, said elements being supplied from a transmitter generator (5) with an alternating current. Some of the alternating current supplied to the first antenna element (1) is delivered by means of a safety conductor (3) directly to the proximity of the point of the second antenna element (2), that the safety conductor (3) is throughout its length spaced from the second antenna element (2).
