Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
As shown in fig. 2, the method for testing an antenna with a Cable line according to an embodiment of the present invention includes:
in step S201, a first testing terminal of the network analyzer is connected to a ground line at a terminal of a Cable line of the antenna.
Specifically, the network analyzer is a microwave network analyzer, and is a comprehensive microwave measuring instrument capable of performing scanning measurement in a wide frequency band to determine network parameters. The network analyzer is a new type of instrument for measuring network parameters, and can directly measure complex scattering parameters of active or passive, reversible or irreversible double-port and single-port networks, and give out amplitude and phase frequency characteristics of each scattering parameter in a frequency scanning mode. The automatic network analyzer can correct errors of the measurement results point by point and convert dozens of other network parameters, such as input reflection coefficients, output reflection coefficients, voltage standing wave ratios, impedance (or admittance), attenuation (or gain), phase shift, group delay and other transmission parameters, isolation, orientation and the like.
As shown in fig. 3, a terminal 111 of the Cable wire 11 of the antenna includes a ground wire and a core wire, wherein the ground wire is generally located at an outer layer, the core wire is located at an inner layer, and an insulating layer material is disposed between the core wire and the ground wire to prevent the core wire and the ground wire from short-circuit failure. The general connection structure adopts a connector, and is connected with a Cable wire in a plugging and unplugging mode directly through the connector. The housing portion of the Cable wire is typically provided as a ground wire. In the application, when the Cable wire is required to be connected with the ground wire of the Cable wire separately, the Cable wire can be connected with the ground wire of the Cable wire through a clamp or other fixing structures.
In a preferred embodiment, as shown in fig. 3, the clip may be an elastic clip. Can be stable through elastic fixture with first test end be connected with the terminal department of the ground wire of Cable line to make things convenient for the staff to carry out subsequent test work.
Of course, for better fixing the clamp, the shape of the clamping part of the clamp can be matched with the shape of the terminal of the Cable wire, so that the clamp can be fixedly connected with the Cable wire more conveniently.
In addition, in order to obtain a more accurate test result, the increased line loss of the connection at the first test end of the network analyzer is needed, and the impedance matching is performed on the connection structure, for example, the impedance of the clamp is needed to be matched.
In step S202, the second testing end of the network analyzer is connected to the core wire of the Cable wire of the antenna at the welding point of the antenna board.
As shown in fig. 3, the structural schematic diagram of the antenna with Cable wire includes an antenna board 12 and a Cable wire 11, a metal wire 121 and a ground wire 122 are disposed on the antenna board, wherein the metal wire 121 is used for collecting radio wave signals and transmitting the radio wave signals. A connecting portion is disposed on one side of the antenna plate 12, and the Cable wire is connected to the antenna plate 12 by welding or the like. When the Cable wire is connected with the antenna board, the Cable wire and the core wire are respectively connected. As shown in fig. 3, the ground wire of the Cable wire is connected to the ground wire of the antenna board, and the core wire of the Cable wire is connected to the metal wire of the antenna board. The connection mode can be a welding structure and the like. In order to facilitate the test and reduce the interference, the distance between the welding point 123 of the core wire and the welding point 124 of the ground wire of the Cable wire is usually greater than a predetermined distance, for example, when the second testing end contacts the welding point 123 of the core wire through the testing thimble, the distance between the welding point 123 of the core wire and the welding point 124 of the ground wire of the Cable wire may be greater than the diameter of the core wire.
Of course, as an alternative embodiment of the present invention, the method may further include:
and a first test end of the network analyzer is selected and connected with the core wire at the terminal of the Cable wire of the antenna, and a second test end of the network analyzer is connected with the ground wire of the Cable wire of the antenna at the welding point of the antenna plate.
In step S203, the antenna with Cable line is tested according to the data collected by the first testing end and the second testing end of the network analyzer.
According to the connection mode, the first test end is connected with the ground wire at the terminal of the Cable wire of the antenna, the second test end of the network analyzer is connected with the core wire of the Cable wire of the antenna at the welding point of the antenna plate, when the welding point of the core wire is in fault, the radio signal collected by the metal wire of the antenna plate cannot be collected in the network analyzer, and therefore whether the fault that the core wire of the Cable wire is in open circuit at the welding point can be accurately judged. When the core wire has an open circuit fault, a oscillogram different from a normal core wire can be collected in the network analyzer, and whether the open circuit fault occurs can be distinguished very obviously and conveniently.
The first testing end of the network analyzer is connected with the ground wire at the terminal of the Cable wire of the antenna, the second testing end of the network analyzer is connected with the core wire of the Cable wire of the antenna at the welding point of the antenna plate, so that repeated plugging and unplugging of the terminal of the Cable wire can be avoided, the first testing end of the network analyzer is connected with the second testing end in a mode of changing a testing position, and the short circuit problem and the welding point welding problem of the Cable wire can be effectively measured.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
