Bandpass Filter using Optimum Short Circuited Stub Technique

Filters are the key components in communication system. In this paper, the description of Ultra Wide Band filter design techniques and to show the different aspects of the design technique used. The optimum short circuited technique is one the technique used to design the Ultra Wide band filter. The word optimum refers to connecting lines between short circuited stubs. These designs have no cross coupling between I/O aliment lines. The input/output excitation is analyzed by this technique to obtain tough wide band coupling. By formulating the resonance conditions of the resonators we get the desired Ultra Wide Band.
