  • Patent number: 10014568
    Abstract: Embodiments described herein relate a mobile communication device and techniques to suppress deterioration of antenna characteristics. The mobile device includes metallic members that are disposed around, or in portions of a casing of the mobile device. The metallic member is grounded directly to a ground plane of the mobile device at a first predetermined position. The grounded metallic member forms a stub line that cancels a flow of electric current though the metallic member. Furthermore, the metallic member is also connected to the ground plane, at a second predetermined location, via a resonant circuit. The mobile device is capable of adjusting a phase of the antenna current flowing through the device, when the mobile device is being operated by a user, and thus suppresses deterioration of antenna characteristics in certain desired frequency bands.

  • Patent number: 9917357
    Abstract: Discussed herein is an antenna system that comprises a feed element and a radiating element that are formed on a dielectric substrate positioned above a circuit board which includes a feed circuit and a ground layer. Specifically, the feed element is disposed within an outer periphery defined by the radiating element. A capacitive coupling is formed between the feed element and the radiating element. With the aforesaid configuration, the antenna system is less affected by the circuit board and interference from other elements that are mounted on the circuit board. Further, manufacturing costs are reduced as compared to the case where the feed element and the radiating element are respectively formed on a front and rear surface of a resin layer.
