Abstract: The embodiments of the disclosure provides a package structure and a manufacturing method thereof, the package structure includes: a die, including a substrate and a device layer, wherein the substrate has a front side and a back side opposite to each other in a first direction perpendicular to a main surface of the die, and the device layer is at the front side of the substrate; a thermal interface material layer, on the back side of the substrate; and a thermal dissipation component, attached to the die through the thermal interface material layer, the die further includes at least one of a heat dissipation filling structure and a substrate recess, the heat dissipation filling structure is embedded in the substrate and has an exposed part exposed at a sidewall of the substrate; the substrate recess is recessed from the back side of the substrate towards the device layer.

Abstract: The present invention discloses a triple-resonant null frequency scanning antenna, which belongs to the technical fields of the Internet of Things and microwave. The triple-resonant null frequency scanning antenna comprises a circular sector magnetic dipole arranged on a medium substrate, and rectangular notches are symmetrically arranged on a sector patch of the circular sector magnetic dipole. The circular sector magnetic dipole is fixed on the medium substrate by a second shorting pin and third shorting pins, an flared angle of the circular sector magnetic dipole is a first central angle, and two third shorting pins are present and are symmetrically arranged on both sides of the angular bisector of the first central angle.

Abstract: The present invention discloses a sector dual-resonant dipole antenna. Radiation elements of the antenna are two identical sector patches. Two identical rectangular notches can be symmetrically arranged or two identical tuning stubs can be symmetrically loaded on the sector patches at positions deviating from the central axis of the two sector patches. Exciting points are symmetrically arranged on sides of the sector patches close to a central axis. The present invention realizes a wide beamwidth radiation characteristic through a two-dimensional sectorial resonator, and then the notches are arranged or the tuning stubs are loaded at appropriate positions of two arms of the sectorial resonator, and thereby a dual-resonant characteristic can be realized within a working band.

Abstract: An imaging device includes objective optics configured to form an image at a focal plane and having an optical axis that intersects the focal plane at an optical center. An image sensor, which includes an array of sensor elements arranged in a matrix of rows and columns, is positioned in the focal plane with a center point of the matrix displaced transversely by at least ten rows relative to the optical center.

Abstract: The server may be configured with two or more than two network cards. The server may advertise a route, which may comprise a network segment address of each local network card and an IP address of the server, to a route neighbor of the server via the each local network card. The server may receive route information, which may comprise an address of a device, from the route neighbor of the server via the each network card. The server may determine a route from the server to the device. An outgoing port of the route may be the each network card. When a packet destined for the address of the device is received, the server may forward the packet via the route. When a link connecting to a network card fails, the server may disable all the routes, outgoing interfaces of which may be the network card.
