Foldable dipole antenna device for cell phone, has dipole antenna retransmitting wave phase-shifted by specific degrees towards hand, where dipole antenna and passive dipole antenna are arranged on insulating support
The device has a passive dipole antenna (1) for receiving a phase wave, where the passive antenna is made of copper. A dipole antenna (2) that is similar to the passive dipole antenna, retransmits a wave phase-shifted by 180 degrees towards a hand. The passive dipole antenna and the dipole antenna are arranged on a flexible insulating support (18) i.e. printed circuit, and have copper tracks. The insulating support comprises an adhesive layer on the back for permitting fixation of the device on a cell phone.
