Abstract
The present disclosure provides an antenna structure, including a feed terminal, an intermediate grounding terminal, a tail grounding terminal, a conductive head section and a conductive intermediate section. The feed terminal is for connecting a feed signal. The intermediate grounding terminal is responsible for conducting to a ground plane via an intermediate impedance during a second operation mode, and ceasing conducting via the intermediate impedance during a first operation mode. The tail grounding terminal is for connecting the ground plane. The head section extends from the feed terminal to the intermediate grounding terminal along a loop. The intermediate section extends from the intermediate grounding terminal to the tail grounding terminal along the loop.

An antenna structure comprising:
- a feed terminal for connecting a feed signal;
- an intermediate grounding terminal for:
- conducting to a ground plane via an intermediate impedance during a second operation mode, and
- ceasing conducting via the intermediate impedance during a first operation mode;
- a tail grounding terminal for connecting the ground plane;

- and
- an intermediate section, being conductive, extending from the intermediate grounding terminal to the tail grounding terminal along the loop.
An antenna structure comprising:
- a feed terminal for connecting a feed signal;
- an intermediate grounding terminal;
- a tail grounding terminal for connecting a ground plane;
- a head section, being conductive, extending from the feed terminal to the intermediate grounding terminal along a loop, capable of supporting a third electromagnetic resonance with two anti-nodes respectively at the feed terminal and the intermediate grounding terminal during a second operation mode;
- and
- an intermediate section, being conductive, extending from the intermediate grounding terminal to the tail grounding terminal along the loop, capable of supporting a second electromagnetic resonance with two anti-nodes respectively at the intermediate grounding terminal and the tail grounding terminal during the second operation mode;
- wherein, during a first operation mode, the head section and the intermediate section are further capable of jointly supporting a first electromagnetic resonance with two anti-nodes respectively at the feed terminal and the tail grounding terminal, without anti-nodes located between the feed terminal and the tail grounding terminal on the head section and the tail section.
