Effect of I Shaped Periodic Structures over Collinear Arms of 150 Degree Bend Substrate Integrated Waveguide
2019
A Substrate integrated waveguide (SIW) wideband band pass filter with 150 degree bend is presented in this paper. Attenuation of higher transmission frequencies are achieved by using array of I-shaped periodic band gap structures at the collinear arms. Six I-shaped slots (three in each arm) are etched over the top conducting layer to achieve the purpose. Several major parameters of these I-shaped structures are studied and presented with detailed outcome. Insertion loss 4GHz) is observed. The filter finds application in microwave X-band and Ku-band radar and satellite systems.
