A Compact Graphene-Based Six-Way Power Divider

In this paper, a novel compact graphene-based six-way power divider is presented. It has planar structure and can be manufactured easily through PCB process combined with laser etching. Circular graphene film is utilized as omnidirectional isolation resistance between arbitrary two output ports, avoiding traditional welding process of fussy lumped resistance. The six-way power divider, realized by double-layer microstrip structure, works at the frequency range from 1.8GHz to 2.8GHz. The final simulation result shows that the structure has a distribution loss of 8dB and an insertion loss of ±0.6dB, the port isolation is always better than 20dB.
