Design of A Novel Compact Planar Six-way Power Divider Using Folded and Hybrid-Expanded Coupled Line

摘要

A novel planar six-way power divider is proposed. Based on the conventional planar microstrip coupled line technology, the proposed compact six-way power divider is comprised of two stages coupled transmission line, which is different to the conventional multi-stage power divider using the same expanded structure, one stage folded asymmetrical two-coupled line, the other hybrid-expanded symmetrical three-coupled line. The design and simulated results have shown that the power divider has a good performance, which are insert loss 8.1±0.2dB from 1.4 GHz to 2.6 GHz, and return loss less than -15dB, isolation less than -20dB at 2 GHz, respectively.
