In this paper, a wideband power divider based on substrate integrated waveguide (SIW) using complementary split-ring resonator (CSRR) and slots is presented. Circular CSRR and two identical slots are engraved in the upper metallic surface of the SIW structure to achieve equal power division over a wideband. A prototype of power divider based on SIW with a 3 dB power division over a wideband is designed, fabricated and tested. Measurement results show that it has return loss greater than 15 dB with insertion loss of 0.89 dB throughout the wideband. The proposed power divider occupies a compact size of 0.950λg× 0.608λg.
