Abstract: A spring antenna structure integrally formed by bending a metallic sheet includes a supporting portion, a grounding radiating portion, and an antenna radiating portion. Two opposite ends of the supporting portion are respectively connected to the grounding and antenna radiating portion. The grounding and antenna radiating portion are formed by bending the supporting portion in a rotating direction. A first angle (?1) is defined between the grounding radiating portion and the supporting portion, and a second angle (?2) is defined between the antenna radiating portion and the supporting portion. 0°<?1<90° and 0°<?2<?1+90°. When the spring antenna structure is pressed and deformed by an external force, the spring antenna structure generates a returning force for returning to the original shape.
