Abstract: A light-transmitting antenna includes a substrate, a first and a second conductive pattern. The first and the second conductive pattern is disposed on a first and a second surface of the substrate respectively. The first conductive pattern includes a first feeder unit, a first and a second radiation unit, a first and a second coupling unit and a first parasitic unit. The first feeder unit is connected to the second radiation unit. The first and the second radiation unit are located between the first and the second coupling unit. One side and the other side of the first parasitic unit is connected to the second coupling unit and adjacent to the first coupling unit respectively. The second conductive pattern includes a second feeder unit, a third coupling unit, a second parasitic unit, and a fourth coupling unit.

Abstract: A light-transmitting antenna includes a substrate, a first conductive pattern, and a second conductive pattern. The first conductive pattern has a first feeder unit, a first radiation unit, a second radiation unit, and a first connection unit. The first feeder unit and the first connection unit are connected to two sides of the first radiation unit. The first connection unit connects the first radiation unit and the second radiation unit. The second conductive pattern has a second feeder unit, a third radiation unit, a fourth radiation unit, and a second connection unit. The second feeder unit and the second connection unit are connected to two sides of the third radiation unit. The second connection unit connects the third radiation unit and the fourth radiation unit. An orthogonal projection of the second feeder unit on a first surface of the substrate at least partially overlaps the first feeder unit.

Abstract: The invention is to provide an adjustable vacuum food storage container, comprising of a base, a socket mounted on the base, and a cover covering the socket; a vacuum controller, a pressure detective means, an out connector power means, a spare battery set, and a power switch are disposed on the base, and an exhaust valve are further added on upper cover; the pressure detective connected to the socket for auto-detecting the accommodation between the socket and the upper cover, and the vacuum controller combined to the pressure detective means for keep it at vacuum state at any moment.

Abstract: The present invention provides an improved steam cleaning device, comprising: a hand-held steam generator, a pole, a platform cleaning polygon housing, constructed by an upper lid and a lower lid opposite to each other, a steam-releasing apparatus disposed at the bottom of the platform cleaning polygon housing, indentation of the upper lid pivoted to clips, at least one wheeled body connected to lift said platform cleaning polygon housing off the floor; and a cleaning tool; wherein said hand-held steam generator can be selectively adapted to the pole, the platform cleaning polygon housing or at least one cleaning tool.
