A modified branch line coupler with ultra-wide harmonics rejection using resonators and open- ended stubs

In this paper, a modified microstrip branch-line coupler (BLC) at 1.6 GHz is designed and simulated. The proposed BLC consists of open stubs and resonators together. The designed BLC correctly works at the operating frequency and suppresses 2nd up to 13th unwanted harmonics. The&#x...
