Description

Antenna assembly

Technical Field

Background

With the progress of wireless networks, today's desktop computers are also often equipped with antennas and connected to network cards to achieve wireless communication, so that the number of wired hubs can be reduced, the use environment can be reduced, wiring can be reduced, and the desktop computers are more concise and comfortable, and have a larger margin in space configuration.

The specifications of the antenna frequency band commonly used at present, for example, WIFI 6E are 2400MHz to 2500MHz and 5150MHz to 7125MHz. There is no particular interference problem in conventional use.

The antenna assembly 1 includes a body 10 and an antenna body 20. The body 10 includes a first wall 11, two first shielding surfaces 13, and two second shielding surfaces 15. The first surface 111 of the first wall 11 is exposed on the outer surface 510 of the desktop computer 500, and more specifically, is usually located on the frame 520 of the desktop computer 500, and is located on a surface where input/output ports (I/O) are provided or a surface that cannot be disassembled, so as to avoid damage to the antenna assembly 1 when a user removes the casing. The antenna assembly 1 may be positioned at the front or rear I/O as shown in fig. 3A, and also positioned laterally as shown in fig. 3B.

The two second shielding surfaces 15 extend symmetrically from the other two sides of the first wall 11 respectively, and connect the two first shielding surfaces 13 and the connecting portion 17.

Referring to fig. 1 and 2 again, the body 10 is of a solid structure, that is, the first wall 11, the two first shielding surfaces 13, the two second shielding surfaces 15 and the connecting portion 17 are solid.

Further, the antenna assembly 1 further includes a fixing base 40, and the fixing base 40 is connected to the metal housing 10B, which may be integrally formed and extends from a bottom portion substantially perpendicular to the first shielding surface 13 or the second shielding surface 15. The fixing base 40 is used for being assembled with the rack 520 of the desktop computer 500, and the shielding layer 30 is further disposed on the surface of the fixing base 40.

In this embodiment, the assembly of the circuit carrier 10A and the metal housing 10B is indirect, the metal housing 10B is assembled with the cover 50, the circuit carrier 10A is located on the cover 50, and the circuit carrier 10A is located between the metal housing 10B and the cover 50 for fixing.

The bottom plate 57 carries the circuit carrier 10A, and is disposed on the cover 50, and the fixing member 55 surrounds three sides of the circuit carrier 10A and is fixed on the bottom plate 57.

Further, a spacer 59 is further disposed adjacent to the second peripheral portion 16 on a side of the cover 50 adjacent to the second peripheral portion 16 to avoid the offset of the circuit carrier 10A.

However, it is to be understood that the above is by way of example only and not by way of limitation. In practice, the cover 50, the assembling and fixing member 55, the fixing member 70, and other elements may be omitted, and the circuit carrier 10A and the metal housing 10B may be directly assembled by clamping.

As shown in fig. 6 to 7, the antenna body 20 includes a peripheral portion 21, a radiation portion 23, a signal feeding portion 25, and a soldering portion 27, wherein the peripheral portion 21 is disposed around the first surface 111 and is directly connected to the first shielding surface 15 or the second shielding surface 17, or indirectly connected to the first shielding surface 15 or the second shielding surface 17 through the conductive film 60, so that the metallic first shielding surface 15 or the second shielding surface 17, or the shielding layer 30 further has a grounding function. The peripheral edge portion 21 surrounds the radiation portion 23.

The radiation unit 23 may be designed in a pattern of various wifi bands, and may be a monopole antenna, a dipole antenna, or the like.
