Substrate integrated waveguide bandpass filter for short range device application using rectangular open loop resonator

The substrate integrated waveguide (SIW) structure is the candidate for many application in microwave, terahertz and millimeter wave application. It because of SIW can integrate with any component one than others structure. A kind components using a filter component, especialy bandpass filter. This research recommended rectangular open loop resonator giving more selectivity be implemented short range device (SRD) frequency region 2.4 - 2.483 GHz. Two types are proposed. First, proposed six resonators while second used eight resonators. simulation results two kinds have insertion loss (S<sub>21</sub> parameter) below 2 dB return (S<sub>11</sub> 10 dB. Fabrication filters was validated by Vector Network Analyzer. measurement 1.32 S<sub>21</sub> parameter at 2.29 GHz S<sub>11</sub> 18 2.26 – 2.32 While has good agreement Its 2.2 2.41 2.47 16.27 2.38 11.5
