  • Patent number: 11289810
    Abstract: A multi-band antenna includes a grounding conductor, a first radiator, and a second radiator. The grounding conductor has a grounding function. The first radiator has a first radiating portion, a second radiating portion, and a feeding portion configured to connect to a signal source. The second radiator includes a third radiating portion, a fourth radiating portion, and a first grounding portion. A length of the third radiating portion or a length of the fourth radiating portion is longer than lengths of first radiating portion and the second radiating portion combined, and the third radiating portion or the fourth radiating portion is radiationally coupled with the first radiating portion and the second radiating portion.
    Type: Grant

  • Patent number: 11081785
    Abstract: An antenna module includes a grounding conductor, a first radiator, a second radiator, and a grounding component. The grounding conductor has a grounding function. The first radiator includes a first feeding portion and a first radiating portion. The second radiator includes a second feeding portion and a second radiating portion. The grounding component is located between the first radiator and the second radiator, and includes a first coupling portion, a second coupling portion, a capacitor, and a first grounding portion. The first radiating portion is spaced apart from the first coupling portion and the second radiating portion is spaced apart from the second coupling portion. The capacitor is located among the first coupling portion, the second coupling portion, and the first grounding portion. The first grounding portion is connected to the grounding conductor.

  • Patent number: 8174453
    Abstract: The present invention is related to a folder-type mobile communication device. The device comprises a first dielectric substrate, a first ground plane disposed on the first dielectric substrate, a second dielectric substrate, a second ground plane disposed on the second dielectric substrate, an antenna element, a metal line, and a band-stop circuit. The antenna element is located near the first ground plane and is electrically connected to a source on the first dielectric substrate. The second ground plane is electrically connected to the first ground plane through the metal line. The band-stop circuit is located either on the first ground plane or on the second ground plane. The band-stop circuit includes a slit, a capacitive element, and an inductive element. The slit is near the metal line.
