5. **驻波换算与S11的关系** S11的dB值可以用来计算驻波比VSWR。当S11的dB值为负时，VSWR可以通过以下公式计算：VSWR = 1 + (10^(S11/20))^2。反之，已知VSWR ...

有了反射系数Г，我们可以根据公式推导出来RL、VSWR等，所以反射系数/ S 11 S_{11} S11​参数是求另外几个参数的基础，反射系数是根据归一化阻抗求得的。我们 ...

查看VSWR 和回波损耗之间的关系。VSWR 值的范围为1.01:1 至3.5:1。

另外，VSWR 又可轉換成另一項射頻參數叫S 參數裡的S11，這項參數被稱為反射損失(Return Loss)為傳輸功率&反射功率的比值(單位dB)，跟VSWR 是同概念，一般(傳輸) ...

大家好，我是RF elements 的Tomasz，歡迎收看新一期的《Inside Wireless》。

... VSWR）: Voltage Standing Wave Ratio回波损耗（RL）:Return Loss，即S11 换算公式：RL=20*log10[(VSWR+1)/(VSWR-1)] 驻波比 回波损耗(dB) 驻波比 回波损耗(dB) 1.01

The ratio of the input to the reflected signal is called the Voltage Standing Wave Ratio (VSWR). This ratio can also be measured in dB, and expressed as Return ...

VSWR is a measure that numerically describes how well the antenna is impedance matched to the radio or transmission line it is connected to.

VSWR is actually a measure of how well or how badly the impedance of a load matches the characteristic impedance of a transmission line or waveguide.
