George Vendelin,in his book(MICROWAVE CIRCUIT DESIGN USING LINEAR AND NONLINEAR TECHNIQUES 2nd Edition Page no. 249 & 250) tells that shunt stub is the only viable option for stub design.The question is why. I guessed it is because we get the ground plane readily available while implementing shunt design using microstrip lines.
Now the choice narrows down to whether it should be open or short configuration.
On discussion, my friend pointed out that there's no standard for what will be defined as short because any 'short' termination will not exactly be short (for eg,by drilling a hole in PCB & soldering will be of a finite length & a finite impedance)
So we concluded that Open Shunt is the most viable choice for shunt design.
Are the views & reasoning expressed here correct?
