Abstract: A wireless communication device includes a casing having a wireless signal penetrating area, an antenna sending a wireless signal through the wireless signal penetrating area, and an electromagnetic lens assembly including a lens barrel and a lens. The lens barrel has a first end and a second end. The first end is closer to the wireless signal penetrating area than the second end. The lens disposed in the lens barrel has an incident surface and an emission surface on an axis of the lens. The incident surface is a flat surface facing the first end. The emission surface is a convex surface and has a curvature, which is not equal to 0, from a perspective of a first axis perpendicular to the axis of the lens, and has a curvature of 0 from a perspective of a second axis perpendicular to the axis of the lens and the first axis.

Abstract: A shielding member adapted to cover a card edge connector that has a card slot for inserting an electronic card includes a shielding cover covering the card edge connector, having an opening disposed in a position corresponding to a jack of the card slot, and including a top plate, an extending plate, and several side plates. The top plate is disposed on a top portion of the card edge connector. The side plates are connected to the top plate and are disposed on several side portions of the card edge connector. The extending plate is located near the opening of the shielding cover and has a connecting portion connected to the top plate and a contacting portion connected to the connecting portion, formed by bending toward the opening of the shielding cover, and being in contact with the electronic card in a direction away from the opening.
