The multilayer structure is a promising technique used to minimize the size of planar microstrip *** the flexible design and incorporation of other microwave components,multilayer band-pass filter results in better and enhanced *** paper introduces a microstrip fifth-generation(5G)low-frequency band of 2.52–2.65 GHz using a parallel-coupled line(PCL)Bandpass filter and multilayer(ML)hairpin Bandpass *** targeted four-pole resonator has a center frequency of 2.585 GHz with a bandwidth of 130 *** filters are designed with a 0.1 dB passband ripple with a Chebyshev *** hairpin-line offers compact filter design ***,they can be obtained by bending half-wavelength resonator resonators with parallel couplings into a“U”*** proposed configuration of the parllel-coupled line resonator is used to design the ML band-pass *** FR4 substrate with a dielectric constant(Er)of 4.3 and 1.6 mm thickness was used.A comparative analysis between the simulated insertion loss and the reflection cofficient of substrates RO3003 and FR4 was performed to validate the eficiency of the proposed filter *** of PCL filter is accom-plished using computer simulation technology(CST)and an advanced design system(ADS)*** PCL Bandpass filter was experimentally validated and a total tally between simulation results and measured results were achieved demonstrating a well-measured reflection *** simulated results obtained by the hairpin ML bandpass filter show that the circuit performs well in terms of Scattering(S)parameters and the filter size is significantly reduced.
