Film type antenna and production method thereof

Abstract

A film-type antenna comprises a plastic film layer, a first adhesive layer, a metal radiator layer and a second adhesive layer. The plastic film layer has a thickness of less than 0.03 mm, and the metal radiator layer has a thickness of less than 0.025 mm. The metal radiator layer is coated in the plastic film, and the film-type antenna can be fixed in a compact communication electronic product by utilizing the characteristic of the plastic film. The film-type antenna can greatly reduce the occupied volume, and can be fixed in the compact communication electronic product with the effective utilization of the space so as to achieve the space-saving effect.

Description

technical field [0001] The invention relates to a thin-film antenna, and more specifically relates to an antenna structure suitable for being attached inside a communication electronic product to save space. Its application range can include mobile phones, notebook computers, digital TVs, automobiles and wireless local area networks, etc. Background technique [0002] Due to the rapid development of wireless communication technology in recent years, mobile phones have become one of the most important communication tools for people. Mobile phones have also developed from the early days of large volume, exposed antenna, dull appearance, and simple functions to the present thin and light, with hidden antennas, and rich shapes such as clamshell type and slider type. , Play MP3 songs and other functions, let the function of the mobile phone not only communicate information, but also upgrade to the realm of multimedia entertainment. [0003] However, as the size of the mobile ph...

Problems solved by technology

[0003] However, as the size of the mobile phone shrinks, the weight becomes lighter, and more functional modules are required to be built in it, so that the available space inside the mobile phone becomes less and less, which also compresses the microwave transmitting and receiving radiators (usually called Radiator) space available for the antenna)

[0004] At present, the FPC antennas on the market are made of PCB board technology. The radiator needs to go through exposure, development, etching, electroplating, post-printing, baking, cutting and other processing processes. The manufacturing process is quite complicated and time-consuming, and the manufacturing cost is relatively high.
