Abstract :
A new method to achieve wide pass-band characteristics on Substrate Integrated Waveguide (SIW) tunnel section is presented. It will be shown that due to the frequency dispersive nature of the effective permittivity in a waveguide, three in-band longitudinal resonant-modes can be excited from the waveguide-feed interaction. Such modes correspond to the Epsilon Near Zero (ENZ) mode, a half-wavelength mode, and one-wavelength mode.
