  • Patent number: 10644382
    Abstract: An antenna assembly includes a side frame, a feed portion, a ground portion, a radiating portion, and a first matching circuit. The side frame defines a first gap to form a first radiating section from the first gap to a side portion. The radiating portion is inside the side frame and connects to the feed portion and the ground portion, the radiating portion is spaced apart from the side frame and connected to the first radiating section. One end of the first matching circuit connects to an end of the first radiating section adjacent to the first gap, another end connects to the ground portion. The feed portion feeds current into the radiating portion, two opposites ends of the first radiating section and the first matching circuit to activate radiating signals in a first frequency band. A wireless communication device employing the antenna assembly is also provided.

  • Patent number: 10566681
    Abstract: An antenna structure includes a metal housing, a first resonance portion, a second resonance portion, an extending portion, and a signal feed source. The metal housing includes a front frame, a backboard, and a side frame. The side frame defines a slot and the front frame defines a groove and a gap. The metal housing is divided into at least an antenna section by the slot, the groove, and the gap. The first and second resonance portions and the extending portion are spaced apart from each other. The first resonance portion and the extending portion are both directly and electrically connected to the antenna section or are spaced apart and electrically coupled to the antenna section. The second resonance portion is electrically connected to the antenna section. One resonance portion is electrically connected to the signal feed source and the other resonance portion is grounded.

  • Patent number: 10498010
    Abstract: An antenna structure includes a metal housing, a first ground portion, a second ground portion, a first feed source, and a coupling portion. The metal housing includes a front frame, a backboard, and a side frame. The side frame defines a slot and the front frame defines a first groove and a first gap. The slot, the first groove, and the first gap separate a first antenna section from the metal housing. The first ground portion and the second ground portion are both electrically connected to the first antenna section and grounded. One end of the coupling portion is electrically connected to the first feed source. The coupling portion is spaced apart from the first antenna section and current from the first feed source is coupled to the first antenna section through the coupling portion.

  • Patent number: 7285630
    Abstract: A novel isoform of tropomyosin is disclosed. The isoform is closely related to epithelial human tropomyosin (hTM) and more particularly to hTM5 except the last coding exon. The novel isoform, is called TC22. Northern blot analysis with TC22-specific probe revealed that normal culture cell lines and normal epithelial tissues expressed very little, if at all, TC22 message, whereas their transformed counterparts and tumor tissues including dysfunction of the alimentary canal, significantly increased the expression of TC22. Assays directed at determining the level of TC22 are useful in diagnostics and therapeutics of dysfunction of the alimentary canal. Specific antibodies and mimics for TC22 are also disclosed for use in diagnostics and therapeutics of dysfunction of the alimentary canal.
