Design methodology of 90° bend half mode substrate integrated waveguide (HMSIW) band pass filter (BPF) is presented in this paper. Edge wall reflections caused due to the waveguide bend has been minimized by providing 135° bend within the waveguide via wall. Array of reactive longitudinal periodic structures are integrated over the HMSIW BPF to obtain transmission zeroes within the pass-band. The elemental properties such as gap between the periodic structure from via wall, gap between group of periodic elements and gap between elemental periodic slots are analysed to formulate their effect over the transmission bandwidth and the stop-band attenuation for each modes of the BPF. Bandwidth > 2 GHz with insertion loss < 1 dB is achieved within all modes of the BPF. The measured results are compared with the simulated outcomes and the concept is validated.
