Abstract :
This paper presents a novel design of 4 GHz substrate integrated waveguide (SIW)radiating bandpass filter using multilayer technique on the Printed Circuit Board.The circular cavity structure using TM010 mode for both filter and rectangular antenna areemployed in the design of this radiating bandpass filter. To realize the technique, modes of SIW filter and microstrip antenna are coupled using rectangular aperture at common ground plane.The simulation result shows good antenna gain and radiation pattern that prove the capability to integrate SIW filter and microstrip antenna directly without requirement of external matching, thus reduce the overall size of the device. To prove the concept, the multilayer structure is fabricated using Rogers RO3003 with dielectric constant, εr = 3. The measured results show good agreement with the simulated results.
