Methods for Antenna VSWR Testing
In the field of wireless communication, antenna Voltage Standing Wave Ratio
(VSWR) is one of the key indicators to measure antenna performance. It directly
affects the signal transmission efficiency and the working stability of the
equipment. Accurate VSWR testing is crucial for ensuring the good operation of
the antenna and the entire communication system. The following are several
common antenna VSWR testing methods to help you better control the antenna
quality.
The reflectometer method is a classic testing method. Its principle is to
calculate the VSWR by measuring the ratio of the signal power reflected by the
antenna to the incident signal power, that is, the reflection coefficient. This
method is relatively easy to operate and has low equipment cost. It is suitable
for occasions where the testing accuracy is not particularly high, such as the
production and debugging of some small communication equipment.
The network analyzer method is a widely used and high-precision testing
method at present. The network analyzer can accurately measure the scattering
parameters of the antenna, which include information related to VSWR. The VSWR
value can be directly obtained through the analysis and processing of the
measured data. This method not only has high testing accuracy, but also can
comprehensively detect the VSWR characteristics of the antenna at different
frequencies. It is suitable for the research and development, production and
quality inspection of various high-precision antennas.
In addition, there are other testing methods, such as the bridge method.
The bridge method measures the VSWR by constructing a specific test circuit and
utilizing the transmission and reflection characteristics of the signal.
Although it may not be as widely used as the previous two methods, it can also
achieve good results in some specific test environments and conditions.
Different antenna VSWR testing methods have their own characteristics and
applicable scenarios. You can choose the appropriate method according to the
actual testing needs and conditions. We have a professional technical team and
