[0054] Figures 9 to 14 The process of forming the electronic device 100 according to the embodiment of the present application is shown.

[0055] Figure 9 The flexible carrier 10 is shown. The top surface of the flexible carrier 10 has an antenna pattern 20, and the bottom surface has a signal input circuit 70 for radiating electromagnetic waves. In some embodiments, the flexible carrier 10 comprises a liquid crystal polymer (LCP) material with a metal circuit layer embedded therein, making the flexible carrier 10 a bendable soft board.

[0056] Figure 10 The antenna pattern 20 is covered with a tape 110 , a plurality of electronic components 30 are formed on the top and bottom surfaces of the flexible carrier 10 , and selective molding is performed to form a covering layer 40 covering the electronic components 30 .

[0057] Figure 11 It shows the formation of a selective shielding structure, that is, a reflective layer 80 is formed outside the cover layer 40 on the upper side of the flexible carrier 10. The reflective layer 80 is used to concentrate the electromagnetic wave signals received and transmitted by the antenna.

[0058] Figure 12 Shows the use of bending tools to Figure 11 The structure shown is bent, wherein the first fixture 121 carries the flexible carrier 10 and provides heat for the flexible carrier 10, the second fixture 122 provides downward pressure for the flexible carrier 10, and the third fixture 123 changes the shape of the flexible carrier 10, bending the flexible carrier 10 from the straight shape shown by the dotted line into Figure 13The shape shown includes a horizontal portion 12 and a non-horizontal portion 14, Figure 12 The figure shows the formation of a non-horizontal portion 14 of the flexible carrier 10, followed by similar formation of the other three non-horizontal portions of the flexible carrier 10. In the embodiments of the present application, a horn-shaped antenna design is fabricated by bending the flexible carrier 10, allowing for the placement of additional electronic components 30 on the non-horizontal portion 14. This allows for the horizontal placement of more electronic components 30 within the electronic device 100, further reducing the form factor in the height direction and improving the space utilization of the electronic device 100. Furthermore, the placement of additional electronic components 30 enhances the antenna's signal transmission and reception efficiency. The bending angle of the flexible carrier 10 can be optimally controlled based on simulation results (e.g., using a 45-degree angle fixture for bending), eliminating dust contamination and burning issues caused by the laser process, reducing material loss, and improving product performance.

[0059] Figure 13 1 shows a cross-sectional view of an electronic device 100 according to an embodiment of the present application. Figure 14 A top view of an electronic device 100 according to an embodiment of the present application is shown. The flexible carrier 10 includes a horizontal portion 12 and a non-horizontal portion 14 disposed around the horizontal portion 12. The horizontal portion 12 is located at the bottom of the flexible carrier 10, and the antenna pattern 20 is disposed on the horizontal portion 12. An electronic component 30 is disposed on the non-horizontal portion 14 and is electrically connected to the antenna pattern 20 via the flexible carrier 10. An angle α is formed between the side surface of the covering layer 40 and the horizontal portion 12. A reflective layer 80 covers the covering layer 40, and further covers the electronic component 30, to reflect electromagnetic wave signals. The reflective layer 80 and the antenna pattern 20 define a transceiver space 90 for electromagnetic wave signals. The antenna pattern 20 is located on the bottom surface of the transceiver space 90.

[0060] from Figure 14 From the top view shown, the reflective layer 80 discontinuously surrounds the antenna pattern 20. The reflective layer 80 is disposed on the side of the non-horizontal portion 14 and further connects to the cladding layer 40 below the non-horizontal portion 14. The antenna pattern 20 of this embodiment is a slot antenna (also known as a slot antenna). The slot 22 is used to excite electromagnetic waves. The antenna pattern 20 is disposed on a first side (upper side) of the horizontal portion 12, and the signal injection line 70 is disposed on a second side (lower side) of the horizontal portion 12, opposite the first side. The signal injection line 70 is used to radiate electromagnetic waves and leak through the slot 22 of the antenna pattern 20.

[0061] Electronic components 30 include passive devices used to assist in enhancing the transmission and reception of signals, thereby improving the antenna's efficiency. Electronic components 30 are located on a first side (upper side) of the non-horizontal portion 14 facing the antenna pattern 20, and also on a second side (lower side) of the non-horizontal portion 14 opposite the first side and facing away from the antenna pattern 20. This fully utilizes the non-horizontal portion 14, accommodating 1.5 times more electronic components 30 and increasing the number of electronic components 30 on the electronic device 100. A reflective layer 80 covers the electronic components 30 located on the first side to reflect electromagnetic wave signals within the transceiver space 90.

The support member 50 is optional and can be used depending on whether additional support is needed in actual conditions. The material of the support member 50 is, for example, epoxy resin.

[0063] Figure 16 Shown with Figure 13 The electronic device 100 of various embodiments further includes a connector 60 disposed on the underside of the non-horizontal portion 14 . The cover layer 40 exposes the connector 60 so that the connector 60 can electrically connect the electronic device 100 to external components. The connector 60 electrically connects the electronic components 30 on the upper and lower sides of the non-horizontal portion 14 through the flexible carrier 10 .
