1. An antenna structure, comprising:
a substrate having a first surface and a second surface, wherein the first surface and the second surface are on opposite sides of the substrate;
a radiating element disposed on the substrate and comprising:
a first radiating portion disposed on the first surface;
a feeding portion disposed on the first surface and connected to the first radiating portion;
a second radiating portion disposed on the second surface and connected to the first radiating portion, wherein a projected area of the second radiating portion projected onto the first surface partially overlaps the feeding portion;
a grounding portion disposed on the first surface and connected to the first radiating portion; and
a third radiating portion disposed on the second surface and connected to the first radiating portion, wherein a projected area of the third radiating portion projected onto the first surface partially overlaps the grounding portion;
a second radiating element disposed on the substrate, wherein the second radiating element and the first radiating portion are separate from each other but couple with each other;
a grounding element connected to the grounding portion; and
a feeding element having a signal terminal and a ground terminal, wherein the signal terminal is connected to the feeding portion, and the ground terminal is connected to the grounding element.
