pls reply.. i need help ..i searched alot but didn't find enough material to make a report :((

Try D.M. Pozars book: "Microwave engineering" Chapter 8 - microwave filters. It explains the basics and moves on to implementations. I think you'll find what you need there .

Pls refer Peter Rizzi, Passive Microwave devices.
