A Substrate Integrated Waveguide Based Filtenna for X and Ku Band Application

In this paper Substrate Integrated Waveguide-based filtenna operating at Ku band is proposed. The model designed on a low loss dielectric substrate having thickness of 0.508 mm and comprises shorting vias along two edges the walls. To realize bandpass filter, secondary are placed close to primary vias. dimension position carefully analyzed for frequencies. fabricated Roger RT/duroid 5880 performance characteristics measured. proposed achieves significant impedance with wider bandwidth in band. also maximum gain 7.46 dBi thus making it suitable Ku-band applications. Waveguide (SIW) Structures possess most advantages over conventional radiofrequency waveguides since they have high power management capacity self-consistent electrical shielding. noteworthy advantage SIW, can able integrate all components same substrate, both passive active components.
