Claim 12:
13. A circuit board structure with a waveguide, the circuit board structure further comprising:
a circuit board, the waveguide disposed in the circuit board, the circuit board comprising a first substrate unit, one adhesive layer, a third substrate unit, another adhesive layer, and a second substrate unit stacked in that order;
wherein the first substrate unit comprises a first dielectric layer and a first conductive layer disposed on the first dielectric layer, the first conductive layer comprises a first shielding area and two first artificial magnetic conductor areas disposed at two sides of the first shielding area; the second substrate unit comprises a second dielectric layer and a second conductive layer disposed on the second dielectric layer, the second conductive layer comprises a second shielding area; the third substrate unit defines a first slot, and the adhesive layer defines a second slot;
wherein the first slot and the second slot communicate with each other to form a cavity, the first shielding area and the second shielding area are disposed on two sides of the cavity, and the cavity having the first shielding area and the second shielding area forms the waveguide.
