A curved and rectangular SIW resonator was designed and then coupled to microstrip transmission line to provide a band reject response in Advanced Design System Momentum RF software. These filters were designed for interference suppression in X-band and simulated on Rogers RO4350 substrate with thickness of 0.508 mm and relative dielectric constant of 3.48. The simulated result was compared with other bandstop filter at X-band and showed a good suppression at 9 GHz region with attenuation of -61.9 dB and -3 dB bandwidth of 90 MHz.}, number={2-5}, journal={Journal of Telecommunication, Electronic and Computer Engineering (JTEC)}, author={Mazlan, Mohammad Hanif and Ahmad, Badrul Hisham and Husain, Mohd Nor and Zakaria, Zahriladha and Shairi, Noor Azwan and Zahari, Mohd Khairy and Hassan, Nornikman}, year={2017}, month={Jun.}, pages={1–5} }
