Perancangan Band Pass Filter Berbasis Substrate Integrated Waveguide (Siw) Un…

This research presents the design of a 28 GHz bandpass filter with achieving 3.8 GHz bandwidth spanning 25.2 GHz to 29 GHz, targeting to use in 5G FR-2 band applications in the n257 and n258 bands. Implemented on a Rogers RT/duroid 5880 substrate with a dielectric constant of 2.2 and 0.508 mm thickness. The filter demonstrates low insertion loss, excellent impedance matching (VSWR close to 1.0)…
