Embodiment Construction
[0028] In the design of mobile phone antenna, the main board of the mobile phone is used as the mirror reference ground of the antenna, and the antenna and the reference ground form a radiation system. According to the antenna principle, there will also be radiated currents on the motherboard, and these currents need to form a reasonable return flow on the motherboard.
[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0030] like Figure 1 to Figure 3 As shown, in the flip phone, the antenna 8 is located at the bottom of the flip phone and is fixed with a plastic bracket. The LCD sub-board 6 and the mobile phone main board 7 are connected together through the flexible circuit board (FPC) 9 of the liquid crystal display (LCD), and one end of the flexible circuit board 9 (FPC) of the liquid crystal display (LCD) is connected with the LCD sub-board 6, The other end is connected to the mai...

The invention discloses a mobile phone which improves a TRP index and a TIS index. The mobile phone includes a mobile phone shell, a main board and an LCD sub-board. The main board and the LCD sub-board are connected with each other by a soft electric board. A ground wire of the soft electric board is connected with an inductance in series. The mobile phone shell is coated with a conducting paint. The grounds of the LCD main board and the sub-board are respectively collected with the conducting paint. The invention also discloses a method for improving the TRP index and the TIS index of the mobile phone. The invention improves the TRP index and the TIS index of the mobile phone by adopting the methods that the LCD FPC is connected with the inductance in series and the mobile phone shell is coated with the conducting paint and connected with the ground, the improvement is realized by the choking the illogical refluence of reference field and changing the dimension of reference field of the antenna. The invention needs not to change a rotary shaft structure, thus avoiding the reliability descending of the mobile phone caused by changing the rotary shaft structure and also avoiding the modeling change of the mobile phone caused by changing the rotary shaft structure; simultaneously, repair of the structure membrane is omitted, thus saving time and reducing protect cost.
Description
technical field [0001] The present invention relates to a mobile terminal technology, in particular, to a mobile phone and a method thereof with improved TRP and TIS indicators. Background technique [0002] Total Radiated Power (TRP) refers to the average value of the external radiation power of the transmitter in the three-dimensional omnidirectional direction of the mobile phone. It comprehensively measures the radiation performance of the mobile phone. The larger the TRP value, the better the radiation performance of the mobile phone. [0003] Isotropic Sensitivity (TIS, Total Isotropic Sensitivity) refers to the minimum average value of the power that the receiver can receive in the stereo omnidirectional direction of the mobile phone, which comprehensively measures the receiving performance of the mobile phone. The smaller the TIS value, the better the reception performance of the mobile phone. [0004] OTA (Over The Air) test aims to verify the connectivity of wirel...
