1. A spring antenna structure integrally formed by bending a metallic sheet, comprising:
a supporting portion having a feeding point, wherein the supporting portion has a first end and an opposite second end; a grounding radiating portion connected to the first end of the supporting portion, wherein the connection of the grounding radiating portion to the supporting portion defines a first bending line, the supporting portion is bent with respect to the grounding radiating portion along the first bending line in a rotating direction, wherein a first angle is defined between the grounding radiating portion and the supporting portion, and the first angle is θ1; and an antenna radiating portion connected to the second end of the supporting portion, wherein the connection of the antenna radiating portion to the supporting portion defines a second bending line, the supporting portion is bent with respect to the antenna radiating portion along the second bending line in the rotating direction, wherein a second angle is defined between the antenna radiating portion and the supporting portion, the second angle is θ2, the first angle and the second angle conform to the following formulas: 0°<θ1<90° and 0°<θ2<θ1+90°; wherein the spring antenna structure is provided with resilience, so that when the spring antenna structure is pressed and deformed by an external force, the spring antenna structure generates a returning force for returning to an original shape. |
