Antenna device

An antenna device, comprising:

• a substrate;
• and
• at least one antenna component, disposed on the substrate and comprising:
• two hook-shaped excitation bodies, wherein the two hook-shaped excitation bodies are spaced apart from each other and symmetrical to each other, opposite ends of the two hook-shaped excitation bodies are respectively located opposite to each other, an end of one of the two hook-shaped excitation bodies has a feeding end, an end of another one of the two hook-shaped excitation bodies has a grounding end, and the feeding end and the grounding end are located opposite to each other;
• a guider, located on a side of the two hook-shaped excitation bodies;
• a reflector, located on a side of the two hook-shaped excitation bodies located away from the guider, wherein a side of the reflector located close to the two hook-shaped excitation bodies has two first straight edges and a curved edge, the two first straight edges are connected to two opposite sides of the curved edge, and the curved edge is concave in a direction away from the two hook-shaped excitation bodies;
• and
• an impedance matching body, comprising an inductor, wherein the inductor is located between the two hook-shaped excitation bodies and the reflector.
