Claim 0:
1. An antenna device, comprising:
a case assembly, wherein a cavity is defined by an interior of the case assembly, and a first side of the case assembly has a slot penetrating the case assembly;
a first waveguide assembly, at least partially located within the cavity and connected to the first side of the case assembly, wherein a projection of the first waveguide assembly to the first side of the case assembly is symmetrically located on two sides of the slot; and
a second waveguide assembly, located outside the case assembly, close to the first side, and connected to the slot, wherein the second waveguide assembly is suitable for transmitting an antenna signal to the cavity through the slot and the first waveguide assembly, wherein
the antenna signal resonates in the cavity and radiates outward from a second side of the cavity opposite to the first side,
wherein the case assembly has an opening on the second side, the case assembly comprises a first conductor layer located on the first side and a first cavity wall structure located between the first conductor layer and the opening, the first cavity wall structure is connected to a periphery of the opening and the first conductor layer, and the cavity is located between the first cavity wall structure, the first conductor layer, and the opening.
