  • Dual-band antenna
    Patent number: 11050149
    Abstract: A dual-band antenna is provided. The dual-band antenna includes a first antenna, a second antenna, and a grounding component. The first antenna has a first feed point for transceiving a first signal. The second antenna has a second feed point. The grounding component is electrically coupled to the first feed point and the second feed point, wherein the grounding component forms a first path and a second path between the first feed point and the second feed point, wherein a first path length of the first path and a second path length of the second path are integer multiples of a first wavelength of the first signal.

  • Communication apparatus, electronic apparatus and antenna adjustment method
    Patent number: 10923809
    Abstract: A communication apparatus, an electronic apparatus and an antenna adjustment method thereof are provided. The communication apparatus includes an antenna system, a tuning portion and a switch circuit. The antenna system includes at least two antenna units. The tuning portion is disposed between the at least two antenna units and includes at least two branch units. The switch circuit is coupled to the tuning portion. The switch circuit switches a conduction from a first one of the branch units to a second one of the branch units according to a switching signal. The switching signal is related to performances of the antenna system. Accordingly, a dynamic and flexible adjustment mechanism can be provided to increase throughput and improve users' internet experience.

  • Multi-band antenna
    Patent number: 10826178
    Abstract: A multi-band antenna including a ground portion, a first radiation portion, a second radiation portion, a feeding portion and a matching portion is provided. The first radiation portion is disposed beside the ground portion, a first gap is existed between the ground portion and the first radiation portion so as to form a first slot, and the first slot has a first open terminal located at the first gap. The second radiation portion is connected to the first radiation portion. The feeding portion is located between the first radiation portion and the second radiation portion. The matching portion is located in the first slot and connected to the first radiation portion and the ground portion. The feeding portion excites the first slot to generate a first resonant mode. The second radiation portion generates a second resonant mode.
