Problems solved by technology

[0004] At present, there are some solutions on the market to solve the balance between left and right hands, such as miniaturizing the lower antenna of the mobile phone to avoid the position of the hand as much as possible. However, this solution is easily affected by the USB, resulting in poor antenna performance; or if Patent No. "2017102245399 Mobile Terminal and Its Antenna System", through the introduction of "false ground", the sensitive area of ​​the antenna system becomes insensitive, so that the grip area is less affected by the hand, but this solution is very important for improving the balance of left and right hands The effect is not obvious

Embodiment

[0026] Example: such as image 3 and Figure 4 As shown, it is a comparative experiment after applying this scheme on a U-shaped groove metal machine. The actual antenna position is the antenna under the mobile phone, the USB interface is in the middle, and the antenna feed point is at the right end of the PCB. image 3 The middle line A is the resonance generated by the ordinary antenna, and the line B is the antenna resonance obtained after debugging after applying this scheme. image 3 and Figure 4 It can be seen that the frequency band GSM1800, WCDMA1, and LTE B1 / 3 where the 1710-2170Mhz band is located has a wider bandwidth than the common solution, and the TRP data of the left and right sides of the LTE B7 band where the 2500-2700Mhz band is located is 4-6dBm different from the common solution. After applying this scheme, the difference in TRP data between left and right hands is about 0.5dBm.

[0027] In the 1710-2170MHz segment, the resonance is wider than the comm...

Abstract

The invention relates to the technical field of a mobile phone antenna, and specifically discloses an antenna scheme used for improving the hand-head data of a mobile phone. The antenna scheme comprises an antenna body, a PCB main board and a parasitic antenna. The antenna body is provided with a feeding point and a grounding point. The feeding point and the grounding point are respectively connected with left and right ends of the PCB main board. The parasitic antenna is connected with the PCB main board. The width and length of the parasitic antenna and the distance between the parasitic antenna and the antenna body directly influence the frequency deviation, the depth and the bandwidth of the antenna resonance. According to the invention, the performance of the antenna is optimized by adjusting the width and length of the parasitic antenna and the distance between the parasitic antenna and the antenna body; left-right hand-head data difference is effectively improved; and left-right hand-head OTA data are controlled within 2 dBm.

Description

technical field [0001] The invention relates to the technical field of mobile phone antennas, in particular to an antenna scheme for improving head and hand data of mobile phones. Background technique [0002] Today, with the development of communication technology, mobile phones have become an indispensable communication tool in people's daily life, and people have higher and higher requirements for the configuration, function, appearance and texture of mobile phones, as well as communication services. At present, most mobile phones use metal shells. And the thickness of the whole machine is getting thinner and thinner, the space left for the antenna is getting smaller and smaller, and the antenna performance test indicators are becoming more and more strict. [0003] OTA (Over The Air) is an air performance test, which is a related standard formulated by CTIA. In the OTA specification, in order to simulate the influence of the user's real hand on the antenna, a standard ha...
