Claim 0:
1. A method for manufacturing a circuit board structure with a waveguide, the method comprising:
providing a first substrate unit, a second substrate unit, a third substrate unit, and two adhesive layers, the first substrate unit comprising a first dielectric layer and a first conductive layer disposed on the first dielectric layer, the first conductive layer comprising a first shielding area and two first artificial magnetic conductor areas disposed on two sides of the first shielding area; the second substrate unit comprising a second dielectric layer and a second conductive layer disposed on the second dielectric layer, the second conductive layer comprising a second shielding area; the third substrate unit defining a first slot, and the adhesive layer defining a second slot;
stacking the first substrate unit, one of the adhesive layers, the third substrate unit, another one of the adhesive layers, and the second substrate unit in that order, causing the first slot and the second slot to communicate with each other to form a cavity, and the first shielding area and the second shielding area to be disposed on two sides of the cavity, thereby obtaining an intermediate body;
pressing the intermediate body, causing the cavity having the first shielding area and the second shielding area to form the waveguide, thereby obtaining the circuit board structure.
