Description
Examples
匹配网络评估参数
Show the evaluation parameters of a default matching network.
matchnet = matchingnetwork; c = getEvaluationParameters(matchnet)
c=1×6 tableParameter Comparison Goal Band Weight Source _________ __________ ______ ________________________ ______ _____________ {'Gt'} {'>'} {[-3]} {[950000000 1.0500e+09]} {[1]} {'Automatic'}
Matching Network From Dipole Antenna
Create a dipole antenna and create the S-parameters of the antenna. This example requires Antenna Toolbox.
d = dipole('长度', 0.103,'Width',0.0022); freq = linspace(0.5e9,2.5e9,1001); sd = sparameters(d, freq);
Alternatively, load S-Parameters from the MAT file
%加载('sparams_dipole.mat')
Create a matching network from the S-parameters.
n =匹配网络('loadimpedance',sd,'Components',3,...'LoadedQ'7'CenterFrequency',2e9);
Get the evaluation parameters of the network.
t = getEvaluationParameters(n)
t=1×6 tableParameter Comparison Goal Band Weight Source _________ __________ ______ _________________________ ______ _____________ {'Gt'} {'>'} {[-3]} {[1.8571e+09 2.1429e+09]} {[1]} {'Automatic'}
Plot the reflection coefficient and transducer gain of the matching network circuit 1 , at a frequency range of 1 GHz to 2.5 GHz.
rfplot(n, (1e9:0.001e9:2.5e9),1);
添加新的评估参数以比较换能器增益的截止值小于-10 dB。使用0.5 GHz至1.5 GHz的频率范围。绘制比较。
n = addEvaluationParameter(n,'Gt','<', -10, [0.5e9 1.5e9], 1); t = getEvaluationParameters(n)

rfplot(n, (1e9:0.001e9:2.5e9),1);
Clear evaluation parameters.
n = clearEvaluationParameter(n,1); t = getEvaluationParameters(n)
