A wideband microstrip stub (short at dc, open at the fund and 2nd harmonic). BW >20%

How to implement a wideband microstrip stub which is short at dc and open at the fundamental and 2nd harmonic?BW > 20% around the fund and 2nd harm?

Hi I am looking for a microstrip stub which is dc short and open at the fundamental and 2nd harmonic? The BW should be more than 20% around fundamental and the 2nd harmonic. Any filter structure is also ok provided is dc shorted at one of the ends.
