DESIGN AND IMPLEMENTATION OF BAND-PASS FILTERS FOR THE 5TH GENERATION WIRELESS SYSTEM

This paper proposes a band-pass filter with center frequency of 4.2 GHz, which can be applied in fifth - generation (5G) mobile communication. Currently, 5G networks are experiencing rapid development and highly regarded as the primary network technology. technology divided into two major ranges. The first range is defined by 3GPP operates below 6 known sub-6 GHz range. second falls approximately between 30 100 GHz. aims to design microstrip By modifying line width, shape, number couplings filter, we achieve desired increase bandwidth. A bandpass was fabricated on an FR4 substrate relative dielectric constant 4.4, overall dimensions 17×5×1.55 mm3.and measured. T Through simulation analysis, it understood that adding inner ring gap improve performance filter.
