Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to an antenna testing method. The specific flow is shown in figure 1. The method comprises the following implementation steps:
it should be noted that the antenna testing method can be applied to a terminal provided with an antenna, such as a mobile phone, a tablet and other wireless communication devices, where no specific limitation is imposed, and each antenna installed on the terminal needs to be subjected to an antenna test, so as to ensure normal communication of the terminal or the wireless communication device.
Step 101: and acquiring the actual conduction power obtained in the conduction test.
Specifically, when the antenna test is performed, an actual conducted power at the time of the conduction test is obtained, where the actual conducted power is determined by conducting the conduction test on a PCB (Printed Circuit Board) on the device, and specifically, the actual conducted power includes a theoretical conducted power and a conducted terminal test error.
The theoretical conduction power of the PCB is a preset value, the theoretical conduction power is related to the specification, materials and the like of the PCB, the actual conduction power is obtained through conduction testing, and the difference value between the theoretical conduction power and the actual conduction power is a conduction end testing error.
It should be noted that, a general wireless communication device is generally provided with one PCB, for example, a mobile phone, only one conduction test is needed, and if the device includes more than one PCB, the actual conduction power of each PCB needs to be determined. In a similar way, need use actual conducted power when carrying out the antenna test, if this equipment has only a PCB board, then carry out the antenna test and use the actual conducted power once, if including more than one PCB board in this equipment, then every PCB board can all determine corresponding antenna power.
It should be noted that the actual conducted power is determined to make the determination of the antenna power more accurate and reliable, and devices of general communication equipment are all disposed on the PCB, so that the actual conducted power of the PCB needs to be obtained to accurately represent the antenna performance, and if the devices on the equipment are disposed on other circuit boards, the actual conducted power is correspondingly determined, where the actual conducted power is only determined by taking the PCB as an example, specifically, the actual conducted power needs to be determined, and no limitation is specifically made.
Step 102: and acquiring the measurement error of the antenna end.
Specifically, the antenna end test error includes a deviation of the antenna itself and an assembly deviation of the antenna; the deviation of the antenna is the difference between the actual size, shape or structure of the antenna and the designed size or structure of the antenna, and if the width of the designed antenna is 2mm, the size of the actually manufactured antenna and the designed antenna have a small error value, such as an error of 0.1 mm; the assembly deviation of the antenna is an error generated in the mounting process of the antenna, which may be an error caused by the mismatch of the antenna slot of the antenna and the antenna.
It should be noted that when the measurement error of the antenna end is obtained, the antenna is already correctly installed in the wireless communication device, and in order to accurately determine the performance of the antenna, the measurement error of the antenna needs to be determined after the antenna is installed in the wireless communication device, and the measurement error of the antenna is already determined after the antenna is installed.
Step 103: and calculating the antenna power according to the actual conducted power, the antenna end measurement error and the theoretical antenna efficiency.
Where antenna power represents the performance of the antenna.
Specifically, the calculation of the antenna power is realized by calculating a sum of the actual conducted power, the antenna-end measurement error, and the theoretical antenna efficiency, and taking the sum as the antenna power. Wherein, the actual conducted power can be expressed as the sum of the theoretical conducted power and the testing error of the conducting terminal, so the antenna power can also be expressed as the sum of the theoretical conducted power, the testing error of the conducting terminal, the theoretical antenna efficiency and the measuring error of the antenna terminal, and the theoretical conducted power and the theoretical antenna efficiency are known values,
in this embodiment, the antenna efficiency is determined by obtaining the actual conducted power, the antenna end test error, and the determined theoretical antenna efficiency, the conduction test may be performed before the antenna is installed or after the antenna is installed, and here, no specific limitation is imposed, and the antenna end measurement error may be directly determined after the antenna is installed in the wireless communication device.
Specifically, as mentioned in step 101, the wireless communication device may include more than one PCB, and the antenna power of each PCB is determined for the wireless communication device including at least one PCB. In addition, the existing terminal device, such as a mobile phone, tends to install more than one antenna, such as a MIMO (Multiple-Input Multiple-Output) antenna, and it is necessary to determine the antenna power corresponding to each antenna.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, in the process of conducting test, the actual conducted power is determined at first, the antenna power is related to the efficiency of the antenna and the actual conducted power of the equipment applied by the antenna, therefore, the actual conducted power is increased in the calculation of determining the antenna power, the current performance condition of the antenna can be represented more accurately, a tester can judge the performance condition of the antenna more accurately according to the antenna power, and user experience is improved.
A second embodiment of the present invention relates to an antenna testing method. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in the second embodiment of the present invention, a specific implementation of the actual conducted power storage after the actual conducted power obtained in the conduction test is acquired is specifically described.
Specifically, as shown in fig. 2, the present embodiment includes step 201 to step 205, where step 201 and step 204 are respectively the same as step 101 and step 102 in the first embodiment, and are not described again here. Further, since the detailed description of step 101 includes step 201 and step 203, step 103 in the first embodiment also requires adaptive adjustment. The method comprises the following specific steps:
step 201: obtaining the actual conducted power of each PCB obtained in the conduction test
Step 202: storing the actual conduction power of each PCB to a preset storage interval
Step 203: setting individual identification codes for actual conducted power of each PCB
Step 204: obtaining antenna end measurement errors
Step 205: acquiring actual conducted power of the corresponding PCB according to the identification code
Step 206: and calculating the antenna power corresponding to the PCB according to the actual conducted power of the PCB, the measurement error of the antenna end and the theoretical antenna efficiency.
Specifically, during the conduction test, for a terminal including at least one PCB, it is necessary to determine the actual conduction power of each PCB, for example, to perform the actual conduction power test on the PCB board in the mobile phone, reserve an independent partition for storing the actual conduction power value in the collection storage area, and allocate an identification code to each actual conduction power data, so as to determine the value of each actual conduction power, for example, write the actual conduction power into the designated mobile phone storage partition through the identification code, and directly call the corresponding actual conduction power according to the designated identification code when performing the antenna test.
It should be noted that the identification code is set to be a numerical value for distinguishing each PCB when there are a plurality of PCBs, and is used to mark the actual conducted power when there is only one PCB.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
