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