Publication number: 20250192433Abstract: An electronic device includes a metal housing and an antenna structure. The metal housing includes a first housing and a second housing. The antenna structure is disposed between the first housing and the second housing. The antenna structure includes a carrier, a radiating element, a grounding metal member, a first grounding extension structure, and a reactive element. A first metal portion of the grounding metal member is electrically connected to the first housing, and a second metal portion of the grounding metal member is electrically connected to the second housing. The first grounding extension structure is connected to the first metal portion and the second metal portion. The reactive element is electrically connected between the radiating element and the second metal portion.Type: ApplicationFiled: August 27, 2024Publication date: June 12, 2025Inventors: SHIH-CHIANG WEI, Ying-Hsuan Chen, HSIEH-CHIH LIN

Publication number: 20250046996Abstract: An antenna structure includes a feeding radiation element, a connection radiation element, a first radiation element, a second radiation element, a first shorting radiation element, a second shorting radiation element, and a carrier element. The feeding radiation element has a feeding point. The connection radiation element is coupled to the feeding radiation element. The first radiation element is coupled to the connection radiation element. The second radiation element is coupled to the connection radiation element. The second radiation element and the first radiation element substantially extend in opposite directions. The feeding radiation element and the connection radiation element are coupled through the first shorting radiation element to a first grounding point. The second shorting radiation element is adjacent to the second radiation element. The connection radiation element and the first radiation element are coupled through the second shorting radiation element to a second grounding point.Type: ApplicationFiled: July 1, 2024Publication date: February 6, 2025Inventors: Guan-Ren SU, Ying-Hsuan CHEN, Hsieh-Chih LIN

Patent number: 8382314Abstract: An LED lamp includes an extrusion which is an elongate extrusion housing. It has an outside lens and a circuit board of elongated shape and mounted to an inside bottom portion of the elongate extrusion housing. A plurality of light emitting diodes can be mounted to the circuit board. A concave lens is mounted to an upper portion of the elongate extrusion housing. The outside lens covers the concave lens forming an outside air gap between the outside lens and the concave lens and a power wire connects to the circuit board. A base end cap receives a wire harness. The wire harness includes power, and the base end cap retains a base end of the outside lens and a base end of the extrusion. A top end cap retaining an end of the extrusion also retains an end of the outside lens.Type: GrantFiled: May 12, 2010Date of Patent: February 26, 2013Inventors: Fred Ou, Ying Hsuan Chen
