Problems solved by technology

Some 3D manufacturing technologies have been developed, such as LDS, two-color injection molding, etc., but the initial equipment investment of such technologies is huge, requiring a lot of money, which virtually increases the difficulty of production. Therefore, it is necessary to find a more economical and feasible way to process manufacture such antennas

Embodiment 1

[0023] The upper and lower surfaces of the plastic housing in this embodiment are respectively distributed with antenna patterns 2 formed by printing conductive ink; the plastic housing is provided with a through hole 4 that runs through the upper and lower surfaces, and the printed on The antenna patterns on the upper and lower surfaces extend into the through hole and are connected to form a continuous conductive path.

[0024] The antenna pattern is printed and distributed on the plane or three-dimensional curved surface of the upper and lower surfaces of the plastic shell.

[0025] In this embodiment, as attached figure 2 As shown, the through hole is a tapered hole, and the ratio of the radius to the depth of the tapered hole is at least 2:1. Preferably, the maximum diameter-to-depth ratio of the tapered hole is (2-10): 1; the antenna pattern printed on the upper and lower surfaces of the plastic casing extends to the inner wall of the through hole and is connected to f...

Embodiment 2

[0033] The difference between the present embodiment and the first embodiment is that the openings on both sides of the through hole 4 are tapered, that is, they are bell-mouthed, and the ratio of the radius to the depth is at least 2:1. Preferably, the maximum diameter-to-depth ratio of the through hole is (2-10): 1; the antenna pattern printed on the upper and lower surfaces of the plastic housing extends to the inner wall of the through hole and is connected to form a continuous conductive line. path. . as attached image 3 As shown, the maximum diameter-to-depth ratio of the through hole is 2:1, and the slope ratio of the bell mouth on both sides is 1:0.3; the tapered hole design of the through hole is also to facilitate the printing of conductive lines, and at the same time, the through hole It can be used as a conduction path for other circuits between the two sides of the plastic casing of the electronic device.

Embodiment 3

[0035] The difference between this embodiment and Embodiment 1 is that: Figure 4 As shown, a copper post 3 is embedded in the plastic case, and one end surface of the copper post is flush with the upper or lower surface of the plastic case; the antenna pattern printed on the upper or lower surface of the plastic case extends to the copper post. The end face of the post and the copper post jointly form a conductive path.

[0036] In an application of this embodiment, the antenna patterns printed on the upper and lower surfaces extend to the end faces of the copper pillars to form a conductive path together with the copper pillars, and the antenna patterns on the upper and lower surfaces are connected through the copper pillars.

[0037]In another application of this embodiment, the antenna pattern printed on the upper or lower surface of the plastic casing on the plane or the three-dimensional curved surface extends to the end face of the copper column and is connected to form...

Abstract

The invention discloses a printing antenna. The printing antenna comprises a plastic shell which serves as an insulating substrate, wherein antenna patterns which are formed by printing conductive oil ink are distributed on the upper surface and / or the lower surface of the plastic shell; a through hole or a copper column which penetrates through the upper surface and the lower surface is arranged on the plastic shell; and the antenna patterns which are printed on the upper surface and the lower surface extend to the inner side wall of the through hole and are connected to form a continuously conductive path, or extend to the surface of the copper column which is embedded into the plastic shell and are connected with the copper column to form a conductive path. By directly printing the antenna patterns in the through hole formed in the plastic shell or on the surface of the copper column embedded into the plastic shell, the upper surface and the lower surface form the continuously conductive path, and connecting wires are not required to be added, so that the printing area of the shell is effectively utilized, and the lightening and thinning development of a product is facilitated; unnecessary pollution caused by chemical plating and electroplating is eliminated; additional investment on the basis of a requirement on environment protection is reduced; and mass production can be realized.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a printed antenna. Background technique [0002] With the increasingly widespread application of electronic devices, coupled with their smaller size and more novel designs, more functions have been implanted, such as Bluetooth, WLAN, WIFI, GPS, FM, RFID, NFC, Zigbee, etc., these The common point of the functions is that they all need antennas to realize. Traditional patch antennas can no longer meet the ultra-thin and compact design requirements of this type of products, and some new processes and technologies have emerged as the times require. [0003] The 3D technology combining electronic and mechanical technology is an innovative method, which can manufacture implanted antenna devices with low cost and small space, and provide better design freedom for industrial design, so as to better meet market demand. Some 3D manufacturing technologies have been developed, such as LD...
