In this paper, a complementary split ring resonator (CSRR) loaded twisted waveguide is proposed. A Double CSRR is inserted in the transverse plane of the waveguide. The analysis and optimization has been done by CST Microwave studio 14.0. The presented antenna shows two 10 dB return loss bandwidth from 10.1-.10.3 GHz and 11.7-12.33 GHz. The gain of designed antenna has 7.82 and 7.4 dBi respectively. The lumped circuit model of presented antenna has been also proposed. © 2017 IEEE.
