Abstract
A planar-transmission-line-to-waveguide adapter is provided, to reduce limitations on bandwidth expansion. The planar-transmission-line-to-waveguide adapter includes a planar transmission line structure includes at least a planar transmission line, a dielectric substrate, and a metal ground having a coupling gap. a gradient waveguide structure includes m dielectric waveguides with gradient sizes, and any dielectric waveguide is surrounded by metal via holes in a dielectric substrate, where m is a positive integer not less than 2. a1st dielectric waveguide in the m dielectric waveguides with gradient sizes is coupled with the coupling gap in the planar transmission line structure. Adjacent dielectric waveguides are connected by using a metal ground, and a radiation patch is disposed between the adjacent dielectric waveguides. A metal ground and a radiation patch are disposed on a surface on which an mth dielectric waveguide comes into contact with a standard waveguide.
