Abstract

This study introduces a differential-mode band-passfilter (BPF) implemented using microstrip topology, specificallydesigned for wideband applications. The introduced filter is designed using branch-line configuration, incorporating input and output (I/O) cross-coupling to enhance performance. Notably, the design achieves an exceptional common-mode suppression exceeding 40 dB while maintaining structural simplicity. To validate its effectiveness, this filter is manufactured in-house and experimentally tested. The measurement responses closely align with theoretical predictions, demonstrating strong agreement and confirming the feasibility of the proposed design.
