Abstract: A mobile device includes a system circuit board, a metal frame, one or more other antenna elements, a display device, a first feeding element, and an RF (Radio Frequency) module. The system circuit board includes a system ground plane. The metal frame at least includes a first portion and a second portion. The metal frame at least has a first cut point positioned between the first portion and the second portion. The metal frame further has a second cut point for separating the other antenna elements from the first portion. The first cut point is arranged to be close to a middle region of the display device. The first feeding element is directly or indirectly electrically connected to the first portion. A first antenna structure is formed by the first feeding element and the first portion.

Abstract: The disclosure provides a filtering device comprising a housing, a blocking member and a screening member. The housing includes a body, an inlet end and an outlet end. The housing forms an accommodation space. The inlet end and the outlet end are respectively formed at two ends of the accommodating space. The inlet end is capable of receiving fluid. The blocking member is capable of splitting the fluid into a plurality of fluids and collecting the non-fluid composition of the secondary fluid having a first size. The screening member is disposed between the inlet end and the blocking member, and the screening member is configured to receive the secondary fluid to limit the non-fluid composition having a second size of the secondary fluid to the screening member. After the secondary fluid passes through the shield and the screening member, the secondary fluid is output from the outlet end.
