    Hi All,

    I am trying to desing a Microstrip bandpass filter using edge coupled line filter technique.

    This filter is a narrow band filter. I did lot of trials to design it but the problem is the Insertion Loss in the band is too high. I am not able to reduce it.

    I want to know that is it true that Edge coupled line filter technique is not suitable for a narrowband filter?

    If it is not suitable then which technique will be suitable :
    a) End coupled structure
    b) Hairpin line structure
    c) Comb line structure

    Can anyone help me in this problem??:(:confused:

    Is there any book or link in the web from which I can get useful information for designing a narrowband filter??
