Abstract: A multi-antenna system is provided. The multi-antenna system includes a first antenna, a second antenna, a tunable circuit, and a frequency-divisional circuit. The first antenna is utilized to implement signals of a first frequency band. The second antenna is utilized to implement signals of a second frequency band. The second antenna is different from the first antenna, and frequencies of the second frequency band are greater than frequencies of the first frequency band. The tunable circuit is utilized to switch the signals of the first frequency band. The frequency-divisional circuit is utilized to suppress harmonics caused by the tunable circuit.

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.

Abstract: Various examples and schemes pertaining to a closed-loop antenna with multiple grounding points are described. An apparatus includes an electromagnetic (EM) wave interface device capable of radiating and sensing EM waves. The EM wave interface device includes a feeding port, a first grounding port coupled to an electric ground, and a second grounding port coupled to the electric ground. A first electrically-conductive path connected between the feeding port and the first grounding port forms a closed-loop antenna. A second electrically-conductive path connected between the feeding port and the second grounding port forms a non-radiative closed-loop path. A length of the first electrically-conductive path is greater than a length of the second electrically-conductive path.
