Abstract
A waveguide structure includes a dielectric layer, a plurality of circuit layers, a plurality of insulation layers, and a conductor connection layer. The dielectric layer has an opening. The circuit layers are disposed on the dielectric layer. The insulation layers and the circuit layers are alternately stacked. The conductor connection layer covers an outer wall of the opening in a direction perpendicular to the circuit layers and connects at least two circuit layers on two opposite sides of the opening. At least the conductor connection layer and a part of the circuit layers define an air cavity for transmitting signals at a position corresponding to the opening.
