This paper extends the mathematical synthesis on chaining Chebyshev polynomials of the second kind for the application of a dual-band microstrip filter. The proposed filter allows the flexibility to place multiple inner band transmission zeros for better inner band rejection without affecting the equiripple characteristics of chained Chebyshev polynomials of the second kind.

The design method allows one transmission zero reduction and can be introduced at different locations within inner stopband.
