Flexible thin antenna and manufacturing method thereof

Abstract

The invention discloses a flexible thin antenna and a manufacturing method thereof. The flexible thin antenna comprises a base plate, a thin-film antenna part and a thin conducting film, wherein the base plate is made of insulation material; the thin-film antenna part is provided with an antenna pattern and a transmitting / receiving module, and is used for transmitting and receiving signals; and the thin conducting film is arranged on the base plate, is wholly or partially connected with the thin-film antenna part and is flexible. In the invention, mainly the thin conducting film arranged between the base plate and the thin-film antenna part is used for improving the adhesiveness between the base plate and the thin-film antenna part under the action of an external force or expansion and contraction caused by temperature change, lowering the resistance and improving the defect that the resistance of the thin-film antenna part can be greatly increased under the action of an external force. Further, the thin conducting film can lower the resistance, and the thickness of the thin-film antenna part can be reduced, thereby shortening the coating time and simultaneously lowering the manufacturing cost.

Description

technical field [0001] The invention relates to a film antenna and a manufacturing method thereof, in particular to a flexible thin antenna and a manufacturing method thereof. Background technique [0002] refer to figure 1 It is a schematic diagram of a flexible thin antenna in the prior art. In the prior art, the flexible thin antenna 1 includes a substrate 10 and a film antenna portion 20 . The substrate is an insulating material, usually a flexible substrate. The film antenna part has an antenna pattern and a transceiver component for sending and receiving signals, wherein the antenna pattern is made of metal material. [0003] Although both the substrate 10 and the film antenna part 20 have the property of being flexible, due to different materials, the film antenna part 20 is often curled, deformed, or even peeled off from the substrate 10 when subjected to external force or thermal expansion and contraction. In addition, when the film antenna 20 is warped or defor...

Problems solved by technology

[0003] Although both the substrate 10 and the film antenna part 20 have the property of being flexible, due to different materials, the film antenna part 20 is often curled, deformed, or even peeled off from the substrate 10 when subjected to external force or thermal expansion and contraction. In addition, when the film antenna 20 is curled or deformed, the resistance value will increase significantly and the electrical properties will change, which will make the antenna effect different from the expected one.
