A Miniaturised power divider with SIW and CSRR has been designed for C band applications. Half mode SIW structure reduces the size, loss and improves the performance, whereas CSRR exhibits band pass response. The power dividers response can be changed by changing CSRR dimensions. The proposed power divider exhibits pass band filter response and an equal power division at 6.8 GHz. The dimension of the power divider is 12mm × 9.8mm × 0.5mm. © 2017 IEEE.
