Hello, i have built a simple coupler which i need to connect to other couplers, but when i extended the legs of the ports I get a drastics change in the results,as shown in the attached photos bellow.
Why it happens, in physics point of view the width of the line changes the port , i have not changed the width only prolonged the length.
what needs to be done to safely connect several componnets?(which the sam copper material)
