Abstract: 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.

Abstract: 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.
