A circuit structure includes a substrate integrated waveguide, a substrate disposed on the substrate integrated waveguide, a waveguide signal feeding element and a ring-shaped conductive element. The substrate integrated waveguide includes another substrate having a waveguide transmitting region, two conductive layers disposed on this substrate and covering the waveguide transmitting region, and at least one waveguide conductive element passing through this substrate and electrically connected to the two conductive layers. The at least one waveguide conductive element surrounds the waveguide transmitting region. One of the conductive layers is located between the two substrates. The waveguide signal feeding element passes through one substrate and one conductive layer between the substrates, and the waveguide signal feeding element extends to the waveguide transmitting region. The waveguide signal feeding element is electrically insulated from one conductive layer. The ring-shaped conductive element is disposed in one substrate and surrounds the waveguide signal feeding element.
