Problems solved by technology

Please reunite figure 2 , image 3 As shown, the traditional production method usually uses magnetic materials, graphite sheets are processed and formed separately, then they are wrapped and made separately, and then pasted together, and finally pasted on the circuit board (that is, the coil) for setting on mobile phone batteries, main boards, On parts such as shielding covers, there are defects such as relatively long processing cycle, thick thickness, low production efficiency, and high cost.

preparation example Construction

[0035] The preparation method of the edge-wrapped composite antenna module of the present invention comprises the following steps: a. making a composite material layer and affixing the outer double-sided adhesive layer; b. affixing the composite material layer on the cladding layer to unify Do hemming.

[0036] The concrete manufacturing method of described composite material layer is as follows:

[0037] When the shape of the multi-layer magnetic material layer and the graphite sheet are consistent, the method of pasting and combining first and then forming (cutting out the shape desired by the customer) is adopted (see Figure 7 );

[0038] When the shapes of the multilayer magnetic material layers and the graphite sheets are inconsistent, adopt the method of first forming each and then combining them (see Figure 8 ).

[0039] The present invention is further described by specific examples below:

Abstract

The invention discloses an edge-covered composite antenna module. The composite antenna module comprises a covering layer, an outer-side double-faced adhesive layer and a composite material layer arranged between the above two layers. The composite material layer comprises a plurality of magnetic material layers, and an intermediate double-faced adhesive layer is arranged between the adjacent magnetic material layers, and the magnetic material layers are stacked with each other through the intermediate double-faced adhesive layers, and the innermost-side magnetic material layer is attached onone side of the covering layer, and the outer-side double-faced adhesive layer is attached on one side of the outermost-side magnetic material layer. The invention also discloses a preparation methodof the edge-covered composite antenna module. According to the invention, the edges of a plurality of magnetic materials are covered simultaneously, so that the materials are saved, the working procedure costs are saved, the efficiency is improved, the product can be made thinner, thus the institutional space of customers is further saved, and products are thinner.

Description

technical field [0001] The invention belongs to near-field communication technology (NFC) and wireless charging (WPC), and in particular relates to an edge-wrapped composite antenna module and a preparation method thereof. Background technique [0002] Near field communication technology (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technologies. It combines inductive card readers, inductive cards and point-to-point functions on a single chip. Identification and data exchange with compatible devices. The NFC antenna is a component used to transmit or receive electromagnetic waves in a radio device. It replaces the guided wave propagating on the transmission line with an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio ast...
