Design of Bandpass Filter for 5G Applications with High-selectivity and Wide Band Rejection
In this article, a single band bandpass filter is proposed. The filter is built using a microstrip resonator with added transmission zeros. The suggested filter is based on a third-order fractal coupled line and two slotted lines. The proposed filter has high selectivity property with a wide band rejection response. The design is simulated by Ansys Electronics desktop (HFSS) full wave simulator. The filter is designed to resonate at a center frequency of 6.1 GHz and instructed on Roger RO4003C which has a thickness of 0.508 mm and a dielectric constant of 3.55. The simulation results illustrate good selectivity, wide band rejection, and a fractional bandwidth of 8.1 % for applications in the International Mobile Telecommunications (IMT) services.
