Abstract
There is provided a substrate integrated waveguide filter having a central region and a peripheral region surrounding the central region, and including: a first substrate; a second substrate opposite to the first substrate; a plurality of conductive support pillars between the first substrate and the second substrate, within the peripheral region, and surrounding the central region, wherein a distance between at least one pair of adjacent two of the plurality of conductive support pillars is less than a wavelength of an electromagnetic wave to be transmitted by the substrate integrated waveguide filter; and a dielectric layer between the first substrate and the second substrate, wherein a permittivity of the dielectric layer is configured to be changed as a strength of an electric field formed between the first substrate and the second substrate is changed to adjust a frequency of the substrate integrated waveguide filter.
