  • Publication number: 20240077749
    Abstract: Smart glasses and position adjusting end piece thereof are provided. The smart glasses include: a wearing body provided with a connecting wire, wherein two ends of the connecting wire extend out of two sides of the wearing body respectively; position adjusting end pieces installed on the two sides of the wearing body, which can be rotated around a first direction relative to the wearing body within a first angle range and maintained at any position within the first angle range, and further can be rotated around a second direction relative to the wearing body within a second angle range and maintained at any position within the second angle range; and hinges installed on an end of the position adjusting end pieces away from the wearing body and are electrically connected to the connecting wire. The smart glasses can fine-tune the shape and adjust the size of the whole smart glasses.

  • Patent number: 10862220
    Abstract: A system and method for an antenna including two or more radiation elements on a side of a substrate; a ground plane on an opposite side of the substrate; and a feeding network including a plurality of branch feeding elements. Each of the radiation elements has one or more feeding ports such that each of the plurality of branch feeding element is connected to a feeding port of a respective one of the radiation elements.

  • Patent number: 9905938
    Abstract: A dual polarized high gain and wideband complementary antenna is presented herein. A dual polarized antenna can include a ground plane, a folded dipole portion electrically coupled to the ground plane, a shorted patch antenna portion including an open end that is electrically coupled to the folded dipole portion, and a metal plate located at a bottom portion of the dual polarized antenna. In one example, the folded dipole portion can include four folded dipoles. Further, the open end of the shorted patch antenna portion can be electrically coupled to the folded dipole portion using the metal plate. Further, the dual polarized antenna can include two ports—each port including a pair of feeding sources, and each feeding source configured to generate an electric dipole and a magnetic dipole. In another example, magnitudes of the electric dipoles can be equivalent, and magnitudes of the magnetic dipoles can be equivalent.
