[Embodiment] The embodiments of the present invention are disclosed in the following drawings. For the sake of clarity, a number of practical details will be described in the following description. However, it should be understood that these practical details are not applied to limit this new type. That is to say, in some embodiments of the present invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic representation. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a top plan view showing one embodiment of a plastic member of a buried antenna in accordance with the present invention. Fig. 2 is a cross-sectional view along line 2 of Fig. 1. As shown, a plastic component 100 with an embedded antenna includes a plastic body 120 and an antenna metal line 140. The antenna metal line 140 is embedded and adhered to the plastic body 120. The plastic body 120 includes an opposing outer surface 122 and an inner surface 124. The antenna metal line 140 includes an antenna body 145 and a signal feed portion 150. The signal feeding portion 150 protrudes from the antenna body 145 and is exposed on the inner surface 124. The distance d1 between the antenna body 145 and the outer surface 122 is "less than the distance d2 between the antenna body 145 and the inner surface 124. - The term "embedded and tightly" as used herein means that the antenna metal line 140 is placed in the cavity of the plastic body 120 mold. The thermoplastic liquefied thermoplastic fills the cavity by a certain injection molding method to fully cover the antenna metal line 140, wherein the cooled thermoplastic forms the plastic body 120 and is not connected to the antenna metal line 140. The seams are fused together into the plastic piece 100 of the embedded antenna of the above 7 M435780. Specifically, the antenna metal line 140 is embedded and adhered to the plastic body 120 to provide a stable fixing manner of the antenna metal line 140, which keeps the relative position of the antenna metal line 140 and the plastic body 120 constant. At the same time, the external configuration of the antenna metal line 140 is also fully protected. For example, for the rolling test (R〇1Ungtest), the vibration test (Vibrati〇n test) and the drop test (Dr〇p test), the plastic part 1 of the embedded antenna has a higher structural resistance. Therefore, it is more able to maintain the stability of the antenna. The above-mentioned plastic body 120 can be any plastic product capable of providing the antenna metal circuit and can be combined with the agricultural product. The preparation method can include, but is not limited to, plastic injection, double injection (Double injecti〇n), Insert molding or any combination of the above. It should be understood that the above description is merely illustrative and is not intended to limit the present invention. The method of the present invention is to have a method of elastically selecting the plastic body 12〇 according to actual needs. Specifically, the configuration of the antenna metal line 140 may directly place the prepared antenna metal line 140 in the plastic body 12, for example, placing the antenna copper foil in the mold of the plastic body 120 for burying or double injection* Process. It should be understood that the above description is merely illustrative and is not intended to limit the present invention. Those having ordinary knowledge in the technical field of the present invention should flexibly select the configuration of the antenna metal line 140 according to actual needs. In the present embodiment, the signal locking portion 150 protrudes from the antenna body 145 and is exposed on the inner surface 124, so that the signal feeding portion ι5〇 can be electrically connected to the electronic device, for example, the motherboard. However, the present invention is not limited to this example. M435780 In addition, in order to optimize the performance of the antenna, it is necessary to try to shorten the antenna, which is the distance between the line 140 and the signal transmitting or receiving end of the outside world. That is to say, it is necessary to shorten the distance between the antenna metal line 14G and the outer surface 122. In the present embodiment, the distance between the antenna body 145 and the outer surface 122 is smaller than the distance d2 between the antenna body 145 and the inner surface 124. For example, the reduction (1) 20 is located at a local thickness between the antenna body 145 and the outer surface 122. However, it should be noted that the local thickness reduction in the cavity of the plastic 12G mold due to the liquefaction of the plastic liquefaction during injection molding is relatively poor, so the partial thickness reduction of the plastic body 120 should not affect the plastic body 120. The yield of injection molding is a prerequisite. Outer surface 122 can be a flat surface. In one or more embodiments of the present invention, the antenna body 145 described above has a convex height Η. The direction of the relief extends from the inner surface 124 toward the outer surface 122. The embossing of the antenna body 145 is caused by the deflection of the antenna copper foil itself. However, the embossing does not penetrate the plastic body 12 to the outer surface 122, so the antenna metal line 140 is relatively easy to pass the electromagnetic interference test. Fig. 3 is a cross-sectional view along line 2 of Fig. 1 showing another embodiment of the plastic member of the embedded antenna according to the present invention. The cross-sectional position is the same as in Figure 2. As shown in the figure, based on the appearance of the product, the plastic component 1 of the buried antenna further includes a lacquer layer 200, and the lacquer layer 200 is applied to the outer surface 122, and the lacquer used may be a matt lacquer or a varnish. Leather paint or any combination of the above. Fig. 4 is a cross-sectional view along line 2 of Fig. 1 showing a further embodiment of a plastic member of the embedded antenna according to the present invention. The cross-sectional position is the same as in Figure 2. As shown in the figure below, the outer surface 9 M435780 = 2 has an embossed pattern based on product appearance considerations. However, this drawing is merely an illustration, and the embossed pattern of the present invention is not limited thereto. The seal of the (4) is determined in advance by the mold, or is on the outer surface 122.

Figure 5 is a top view of another embodiment of the return of the (10) antenna of (4). 6A to 6C are cross-sectional views showing the line segment 6 along the line (4) 5 in accordance with the production flow of the embodiment of Fig. 5. As shown in the figure, the plastic piece 100 & of the built-in antenna comprises a plastic inner casing 160, an antenna metal line 140 and a plastic outer casing 18〇. The plastic inner casing (10) includes an outer surface 162, a second outer surface 164, a first inner surface 166, and a second inner surface! 68 and through hole 170. The second outer surface 164 is adjacent to the first outer surface 162. The first inner surface 166 is opposite the first outer surface 162. The second inner surface (10) is opposite the second outer surface 164 and adjacent the first inner surface 166. The through hole 17 is penetrated through the first outer surface 162 and the first inner surface 166. The antenna metal line 14 is disposed on the first outer surface 162 and the second outer surface 164. The antenna metal line 14A includes an antenna body 145 and a signal feed portion 150. The signal feeding portion 15 protrudes from the antenna body 145 along the through hole 1 and is exposed to the first inner surface 162. The plastic outer casing 18 is tightly wrapped around the antenna metal line 140, the first outer surface 162 and the second outer surface 164. The thickness d3 of the plastic outer casing 180 is smaller than the thickness of the plastic inner casing 16 本文. The term "closed coating" means that the antenna metal wire 14 〇 and the plastic inner casing 160 are placed in the cavity of the plastic casing 18 〇 mold. The thermoplastic liquefied thermoplastic fills the cavity by a certain injection molding method to fully cover the antenna metal line 14 and the plastic inner casing 16 , wherein the cooled thermoplastic forms a plastic outer casing 18 盥 and the antenna ^ The line 140 and the plastic inner casing 16 are fused together without joints into the plastic piece 100 of the M435780 embedded antenna described above. The difference between this embodiment and the foregoing embodiment is that the plastic body 120 is replaced with the plastic inner casing 160 and the plastic outer casing 180 by a process of secondary injection molding. Specifically, the plastic inner casing 160' is provided as shown in Fig. 6A via the first injection molding. Next, as shown in Fig. 6B, the antenna metal line 14 is disposed on the first outer surface 162 and the second outer surface 164. In the present embodiment, the signal feeding portion 150 protrudes from the antenna body 145 along the through hole 17 and is exposed to the first inner surface 162, so that the signal feeding portion 15 can be electrically connected to the device, for example, the motherboard. However, the present invention is not limited to this example. Specifically, the antenna metal line 140 can be directly formed on the first outer surface 162 and the second outer surface 164 of the plastic inner casing 160, and the method can be included, but not limited to: printing, bronzing, transfer, sputtering, Any combination of processes such as plating, plating or laser. The antenna metal line 14 can also be disposed directly on the first outer surface 162 and the second outer surface 164 of the plastic inner casing 160. For example, the antenna copper foil is placed on the inner plastic shell 160. The first outer surface 162 and the second outer surface ι64, the combination of the antenna copper foil and the plastic inner casing 160 become a semi-finished product. The semi-finished product is placed in a mold of the plastic casing 180 to be buried and processed. However, the present invention is not limited to this. In the embodiment of the method for manufacturing the antenna metal line 140 as a laser process, the material of the inner plastic shell 160 may be a polycarbonate material (PC) or a liquid crystal polymer (LPP). , Phenylpropanolamine (PPA), Acrylonitrile Butadiene Styrene (ABS), Polypropylene M435780 (Polypropylene; PP), Syndi〇tactic polystyrene · SPS), poly(p-lyethylene terephthalate; PET) or polybutylece terephthalate (PBT) or any combination thereof. Then, by another injection molding, the plastic outer casing 18 is tightly covered, and the metal line 140, the first outer surface 162 and the second outer surface 164 are shown in Fig. 6C. The structure shown above provides a solid state of the antenna metal line 140 t疋, which maintains the relative position of the antenna metal line 14〇 to the plastic inner casing 160 and the plastic outer casing 180 constant. At the same time, the outer configuration of the antenna metal line 140 is also fully protected. For example, for the rolling test, the vibration test and the drop test, the plastic component 100 of the buried antenna is more stable in maintaining the performance of the antenna because of its higher structural resistance. In addition, in order to optimize the performance of the antenna, it is necessary to try to shorten the distance between the line 140 and the signal transmitting or receiving end of the outside. In other words, it is necessary to reduce the thickness d4 of the plastic outer casing 180. In the present embodiment, the thickness of the plastic case 1δ〇 is smaller than the thickness d4 of the inner plastic case 16〇. The need, because the thermoplastic liquefied thermoplastic during injection molding flows through the mold cavity of the plastic peripheral 180 mold is relatively poor, so the thickness d3 of the plastic outer casing 18〇 should not affect the injection molding of the plastic outer casing 180 The rate is premise. In the present embodiment, the plastic outer casing 180 has a design surface 181. This design surface 181 can be a flat surface. In the present invention - or in various embodiments, the antenna body 145 described above has an embossed south Η. The antenna body 145 is embossed due to the antenna metal line 12 M435780 3: two unmeaning 'for example, the plating film is too thick and the laser engraving is incomplete; or the line (4) itself is deflected by the floating L. These embossing 1 white 40 The plastic case 18 is folded to the design surface 181, so the antenna metal line is tested by electromagnetic interference.

The signal feeding portion 15 is exposed at the position of the through hole Π0. The thickness of the plastic outer casing 18 turns is smaller than the thickness d4 of the plastic inner casing 160. As used herein, the term "adhesive" means that the antenna metal wire 14" and the plastic casing 180 are placed in the cavity of the plastic inner casing 16 , mold, and the liquefied thermoplastic is filled by a certain injection molding method. Full cavity, to fully cover the antenna metal circuit 丨4〇 and the plastic case 18〇, wherein the cooled thermoplastic forms the plastic inner casing 160 and is seamlessly integrated with the antenna metal ^ 13 M435780 shell 18° The difference between the method and the foregoing embodiment is that the position of the antenna metal line 1 is changed from the plastic inner casing 160 to the plastic outer casing 180. Specifically. The plastic outer casing 180 is provided via the first injection molding as shown in Fig. 8A. Next, as shown in the figure, the antenna metal line 14 is disposed on the first inner surface 186 and the first inner surface 188. Specifically, the antenna metal and 140 may be configured to make the antenna metal. The line 14G is directly grown from the I to the ground to the first inner surface 186 and the second inner surface 188 of the plastic outer (10). The method can be included, but is not limited to: printing, gold, transfer, and extinction. Any combination of post-processes such as recording, chemical ore, electric money or laser engraving. The configuration of the antenna metal line 140 may also be directly placing the prepared antenna metal line 140 on the first inner surface of the plastic casing 18 186 and The second inner surface 188 is formed by, for example, placing an antenna copper foil on the first inner surface 186 and the second inner surface 188 of the plastic outer casing 180, so that the combination of the antenna metal line 14 and the plastic outer shell 180 becomes a kind The semi-finished product is placed in a mold of 160 in the plastic to be buried and exposed. However, the present invention is not limited thereto. The method for manufacturing the antenna metal line 140 is a laser processing method. The material of 180 can be polycarbonate (p〇iyCarb〇) Nate; PC), Liquid Crystal Polymer (LPP), Phenylpropanolamine (PPA), Acrylonitrile Butadiene Styrene (ABS), Polypropylene (Polypropylene) PP), Syndiotactic 14 M435780 polystyrene (SPS), polyethylene terephthalate (PET) or polybutylene terephthalate (Polybutyleceterephthalate; PBT) or any combination of the above, and the material of the plastic inner casing 160 may be a general plastic. Then, 'through another injection molding', the inner plastic shell 16 is closely adhered to the antenna metal line 140, the first inner surface 186 and the first The inner surface of the inner surface 188 is as shown in Fig. 8C. The structure shown above provides a stable fixing manner of the antenna metal line 140, which makes the antenna metal line 1々 and the plastic inner φ case 60 and the plastic case 18 The relative position remains constant. At the same time, the external configuration of the antenna metal line 140 is also fully protected. For example, for rolling test, vibration test and drop test, The embedded knee-shaped knee 100 has a relatively strong resistance to the structure, so that the stability of the antenna performance can be maintained. In the present embodiment, the 'signal feeding portion 150 is exposed to the through hole 170' so that any electronic device can borrow The signal feeding portion 150 is electrically connected to any of the through-holes n〇.
