Design of microwave components over planar integrated circuits requires flexibility in terms of compactness and adept performance. To aid this requirement design and analyses of multi-band microwave bandpass filter operating in frequencies 13.8–15.0 GHz, 15.1–17.95 GHz and 18.0–19.7 GHz using substrate integrated waveguide (SIW) has been proposed in this paper. Transmission zeroes arising due to periodic rectangular slots are intended to create separation between the successive passbands to eliminate possibility of co-channel interference. Periodic reactive slots are analysed in details to provide greater insight over the controlling parameters of the BPF. The experiments are carried out over 90° bend SIW structure which provide more compact layout as required in microwave integrated circuits. Nearly 35% compactness is achieved by using 90° bend compared to planar structure without waveguide bend. Transmission bandwidth and stopband performances of the proposed BPF are enhanced on the basis of intense study of the waveguide bend as well as periodic slots. Insertion loss within all passbands is obtained in between 0.3 and 0.9 dB. The designs are fabricated using Neltec 3.2 NH9320 substrate with tanδ = 0.0024 and thickness of 30 mils. Measured results testify the simulated outcomes.
