In this paper, we proposed a wideband spoof surface plasmon polariton power divider with simplest odd ratio (a power divider with 3 output port) by a hexagonal ring unit cell and good isolation between output ports. One of the most important properties of SSPP, is created electromagnetic wave with high confinement to collision between metal and dielectric. From this reason, performance of SSPP lines are better than microstrip lines and also, curve path loss in SSPP line is less, in comparison with common transmission line. In order to realized proposed power divider, firs of all we design a new sub-wavelength hexagonal cell and considering a plasmonic waveguide with the periodic unit cell and investigated effect of different substrate with different thickness on scattering parameter, and shows in the best case on rogers4003c with thickness of 0.2mm, we have a transmission line with excellent operation in range of 3 Ghz to 11.8 Ghz with fractional bandwidth of 118.91%. In the next step, we design an equal power divider with two output ports, that have good performance in the range of 2.5 Ghz to 10 Ghz with fractional bandwidth of 120%. In the last step, we design and simulated proposed power divider with 3 output ports that have good operation from frequency of 2 Ghz to 7 Ghz with fractional bandwidth of 111%.
