| Abstract: |
| The first-order approximation of the scattering parameters and VSWR of quarter-wave stripline couplers at center frequency is obtained.Based on the definition of sensitivity,the sensitivity expressions of coupled(S21)and through(S41)outputs related to the parameters of electricity are deduced.Comparison results from programme with that from simulation software of Ansoft company show the correctness and validity of the expressions. |
