In recent years, researches on telecommunications technology are being carried out and involve all aspects of activities. In addition to supporting existing devices, a connection is required to always be connected. Filters can be made using waveguide that can be used at high frequencies. In this research, the development and characterization of a rectangular waveguide with dielectric split ring resonator (SRR) and complementary split ring resonator (CSRR) substrate which works in TE10 mode is carried out. In a BSF square wave based on CSRR, the thickness of the ring, the distance between the rings and the distance of the ring affect the filter bandwidth response by changing the value of return loss and insertion loss. The type of waveguide use is WR90. Meanwhile, SRR and CSRR are mode in two layers of dielectric Arlon Diclad substrate with a thickness of 1.6 mm. In this study, 3 stages were carried out using simulation. The first study showed the results of the BPF square wave characterization were 7.43 GHz with 2% fractional bandwidth, S21 around -1 dB and S11 below -10 dB in the frequency range of 7.33 GHz - 7.53 GHz. The second study showed the results of filter characteristics with a bandwidth of 0.22 GHz, fractional bandwidth of 2.9%, S21 around -1 dB and S11 below -10 dB at the middle frequency of BPF 7.43 GHz from the frequency of 7.33 GHz – 7.53 GHz. The third study was conducted on a BSF square wave based on CSRR bandwidth of -3 dB of 0.15 GHz and fractional bandwidth of 5% at a center frequency of 13.5 GHz with a frequency range of 13.3 GHz up to a frequency of 13.7 GHz while the measurement results on bandwidth of 0.1 GHz in the middle frequency of 13.6 GHz with a frequency range of 13.3 GHz up to a frequency of 14 GHz
