This article presents the design of microstrip parallel-coupled line bandpass filters (BPFs) for fifth-generation wireless communication application. The BPFs are designed and optimized at center frequencies of 5, 15, and 28 GHz via the use of Keysight's Advanced Design System (ADS) 2015 simulator. Initial lumped-element BPFs are presented prior to the realization using microstrip parallel-coupled line technique with the implementation of Rogers RO4003C substrate. Both performances are compared and discussed. The microstrip parallel-coupled line BPFs have optimal average performance of 8.59% bandwidth with insertion loss of 1.53 dB and return loss greater than 12 dB.
