Due to the small size of the mobile terminal antenna, it is difficult to achieve ultra-wideband, and its resonant frequency is generally narrow, which can still meet the design requirements in a free space state. The interference of the human body will cause the shift of the resonant frequency of the antenna, reduce the radiation efficiency of the antenna, and cause a serious decline in the performance of the antenna, thus affecting the call or data service
Although there are related technologies at present, most of them are improved by adjusting the matching method between the main channel of the radio frequency signal and the antenna, which brings about a high demand for the output power of the radio frequency power amplifier, thereby additionally increasing the heat of the mobile terminal system. consumption, so far it is not the best solution
