ABSTRACT:
A device for a set of radio communication equipment to reduce electromagnetic energy absorbency of a human body, it suits especially the equipment of a mobile phone, a Blue Tooth or a PDA etc. The standing wave ratio at a point1is set to be higher than that at a point2of the first working frequency of a multi-frequency wave band, so that the SAR value can be largely lowered. In a preferred embodiment, a point1of the first working frequency has 880 MHz, while a point2has 960 MHz.
