Abstract
In this paper, a compact microstrip lowpass filter (LPF) using triangle-shaped resonators is presented. The designed LPF includes three symmetric triangle-shaped resonators to provide a suitable passband and sharp response. A suppressing unit composed of several suppressing cells is designed to obtain a wide rejection band and low insertion loss in the passband. The fabricated LPF has been measured and indicts that it has â3â¯dB cut off frequency at 5.15â¯GHz. The rejection band has been expended from 5.51â¯GHz to 43.2â¯GHz with maximally flat return loss in this region nearby to 0â¯dB. Also, simulation and experimental results show that the proposed filter has a very flat group delay in the passband, which is the minimum value in comparison with the published works since 2017.
