[ How to use ]

1. Input the parameter of the circuit board and center frequency. 2. (1) When the characteristic impedance (Zo) of the line width (w) is calculated. Input w, and click on [ Analyze ] button. (2) When the line width (w) of the characteristic impedance (Zo) is calculated. Input Zo, and click on [ Synthesis ] button. 3. A calculation result is indicated. [ Note ]Calculation precision gets bad outside the following range. * er=2.2~9.7 --- W/lambda : 0.0015~1.0 * er=9.7~20.0 --- W/h : 0.020~1.0
