The need for the compactness of microwave filter at high frequency application has leadto the design of microwave planar band pass filter which passes certain range of frequencies. The aim of this paper is to study and implement a compact microwave planar band pass filter operates in 3.1GHz-10.6GHz which is the ultra-wide band range. It uses multiple mode resonator (MMR) and inter digital coupled lines to improve upper stop band performance and coupling degree. Simulation of the proposed microwave filter structures is done with the help of HFSS (High Frequency Structure Simulator) software.
