dc.description.abstractIn this paper, a Substrate Integrated Waveguide (SIW) band pass filter loaded with a square Complementary Split Ring Resonator (CSRR) etched with Defected Ground Structure (DGS) is proposed. SIW is a promising candidate for the design and development of various microwave and millimeter wave components useful in communication systems. Due to the evanescent mode propagation and TE10 mode of the cavity, dual band (5.57/7.84 GHz) filtering is achieved with a 3-dB fractional bandwidth (FBW) of 6.8% and 4.1% respectively. The dual bands achieve a low insertion loss of 1.8 dB and 2 dB respectively. Cursor head DGS improves the out of band rejection to a greater level. The configuration is investigated with its corresponding circuit and simulated using Computer Simulation Technology (CST) software. The prototype is fabricated using a Rogers substrate with εr of 3.5 and tested. This prototype finds its application in C band satellite communication systems. The measured results are consistent with the simulated ones.
