Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] refer to figure 1 As shown, it is a schematic diagram of an application environment of a preferred embodiment of the antenna performance optimization method of the present invention.

[0050] In a preferred embodiment of the present invention, the antenna performance optimization method is executed by a test terminal 1, and is used for calibrating the terminal device 2 to be tested, so that the antenna 21 of the terminal device 2 to be tested transmits in the same frequency band. The power (totalradiation power, TRP) index is not up to standard. For example, in the case of some poor channels at this frequency, calibration compensation is performed on the radio frequency conducting end 20 of the terminal device 2 to achieve the coupling of t...

Abstract

An antenna performance optimization method, comprising: measuring the radio frequency conduction power and transmission power of multiple channels in a frequency band at the radio frequency conduction end in the terminal equipment to be tested and the coupling end of the antenna; according to the radio frequency conduction power and transmit power, calculate The power loss of each channel in the frequency band; according to the power loss of each channel, calculate the compensation value of each channel; according to the compensation value of each channel, calculate the actual radio frequency of the radio frequency conducting end in each channel conduction power; and transmitting the actual radio frequency conduction power of each channel to the terminal device under test, so that the radio frequency conduction end of the terminal device under test performs radio frequency conduction according to the actual radio frequency conduction power of each channel. The invention also provides an antenna performance optimization system. The invention performs calibration and compensation on the radio frequency conduction end of the terminal equipment to be tested, so as to achieve the purpose of flat power in the same frequency band of the antenna coupling end.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an antenna performance optimization method and an antenna performance optimization system. Background technique [0002] Due to the limitations of mobile phone structure and materials (metal back shell), etc., it is more and more difficult to debug mobile phone antennas. Especially for mobile phones with metal back shells, due to the influence of metal, it is more difficult to debug the antenna, and the efficiency of the antenna at different frequencies is inconsistent. Click on the possibility of intermittent call sound or even dropped calls. [0003] The transmit power (total radiation power, TRP) index of the antenna is not up to the standard, and sometimes it is necessary to increase the conducted radio frequency to make up for it. For the Qualcomm platform, if it is the same frequency band, it can be solved by modifying the NV to increase the power of the entire frequen...
