A electromagnetic wave preventing cover of an mobile phone handset is covered to a casing of a handset and is connected to the antenna seat hole of the handset, so that the transmitting antenna of the mobile phone handset for emitting electromagnetic radiation is far away from the brain, and thus, the harm of the electromagnetic wave to the brain is reduced. A cover has a space for enclosing the mobile phone handset, and has a slot at the front surface of the cover for extending the communicating covering plate of the handset, and the cover has an opening for receiving the handset into the cover. A terminal serves to insert into the antenna seat hole of the mobile phone handset. An antenna is adhered to the outer surface of the communicating covering plate of the handset. A micro-wave shield coaxial cable is fixed within the cover and has an end connected to the terminal and another end connected to the planar antenna. Thus, the electromagnetic wave preventing cover of an mobile phone handset is covered to a casing of a handset and is connected to the antenna seat hole of the handset so that in communication. The receiving and transmitting source (i.e. antenna) is placed at the position far away from the user's brain and is below the outer side of the protecting cover. Therefore, the transmitting antenna of the mobile phone handset for emitting electromagnetic radiation is far away from the brain, and thus, the harms of the electromagnetic wave to the brain and hand are reduced.
A electromagnetic wave preventing cover of an mobile phone handset being covered by a casing with a free openable and foldable communicating covering plate and being connected to an antenna seat hole of the handset, so that a transmitting antenna of the mobile phone handset for emitting electromagnetic radiation is far away from the brain of an user, and thus, the harm of the electromagnetic wave to the brain is reduced;
An electromagnetic wave preventing cover of an mobile phone handset being covered in a casing and being connected to an antenna seat hole of the handset, so that a transmitting antenna of the mobile phone handset is far away from the brain of an user in communication, and thus, the harm of the electromagnetic wave to the brain is reduced;
An electromagnetic wave preventing cover of an mobile phone handset being to a casing and being connected to an antenna seat hole of the handset, so that a transmitting antenna of the mobile phone handset is far away from the brain of an user in communication, and thus, the harm of the electromagnetic wave to the brain is reduced;
