Hi everyone,
I am tryin to define a lumped port, when I assigned a lumped port, I got this error
"An integration line must be defined for lumped ports"
Can anoyone tell me what should I do ?
 

You should assign integration line. In the option click make new integration line then choose two points on the lumped port to assign the integration line. The integration line will be indicated as an arrow. Hopw this will help

Ok I understand I have to assign an integration line, but I didn't manage to do it properly. I am said that this filter contains two lumped port (I think this is a kind of source ) as shown in the picture. Circled 1 indicates the first lumped port and circled 2 indicates the second lumped port as well. Questions 1 : I have no idea of drawing an integration line, for example Which way should the arrow's head go to?Is there a rule to calculate this ? What would the lenght of the arrow be ?
Question 2: I assigned an integration line as shown in the picture and I got any error message, then I tried to draw another integration line opposite of the other integration line ( circled 2 ), but I get this error "Lumped Port Overlap..." What should I do ?
 

You will have to draw a ground plane below the substrate and filter conductor on the top of it. Then you should draw a rectangle whose width is equal to width of the microstrip and length is equal to substrate height as shown in the fig.
