New description: [New technical field] This creation is related to the structure of a touchpad with an antenna, especially a combination of a planar antenna and a touch panel, so that the touchpad can reduce the touch Input and wireless signal transmission and reception functions. [Prior Art] At present, the application of wireless communication technology is very extensive, and it is extended to various different electric devices. The system is a sub-device of the money belt, and the wireless communication function is already a must for the product; Product design touch, portable mobile electronic devices such as mobile phones, laptops and tablets, in addition to the variety of electronic components, the functions are gradually diversified, are light and easy to carry, and focus on products The lion is highly sexual, so the red is not the result of the wireless communication antenna to make the protruding case settings, and most of them adopt the hidden design; currently mobile phones, laptops and tablets are used to discuss wireless electronic devices. The lightness and aesthetics of the product, so most of its antennas use a hidden design; however, due to the diversification of product features and the small size of the external factors, the available space is reduced, resulting in the design and assembly of the hidden antenna: Difficult, in addition, ' _ days _ signal transmission and reception is easy to be shielded and interfered by the metal surface layer The electronic components of the electronic housing are made of plastic or other non-metallic materials, but usually the physical or chemical properties of such materials, such as hardness, impact resistance, corrosion resistance, etc. The metal material is incomparable, and the color and surface quality of the metal material are not the same as that of the other materials. Because it can't be a gold material, the wireless electronic device suffers from many limitations in the design and application of the casing. . In view of the above-mentioned shortcomings, the common practice is: for example, the side of the side of the electronic product casing is arranged - the metal ring frame is used as an antenna, but when the hand is held or touched, the metal often causes serious interference. The transceiver function is unstable. For example, some electronic products are made of metal materials or composite materials containing metal materials. However, the housing parts with hidden antennas must be specially made of non-metallic materials to prevent the transmission of signals. The performance is shielded and interfered with, but different materials _ body parts will cause huge differences in color and surface texture, seriously detracting from the aesthetics of the product; for example, 'patent application number Lake 21 side "multi-function trackpad" case B exposed - species The bottom surface of the substrate of the board is provided with a circuit for the touchdown, and the structure of the planar antenna is provided on the outer side. However, because the thickness of the film layer of the circuit is different from the thickness of the film, the surface of the substrate is formed on the bottom surface of the substrate - an uneven surface. The result is not only the closing of her after the light (four) plus, for example, the combination of the bottom layer of the protective layer, or even the touchpad Twisting deformation, Further, when the mounting without significant problems in the use of the foreground 'if the entire laying ramp' will produce optical interference phenomena Newton ring or the like, resulting in deformation of the display image, blurring distortion and color distortions. [New content] This creation mainly provides a touch panel structure with an antenna that hides the planar antenna on the bottom surface of the job board. This makes the hard board passable for touch input, and also has the side of the wireless Wei transmission. , reducing the space inside the antenna, avoiding interference and removing the limitation of the casing f; the plane M425335 line is placed in the recessed area of the substrate to make the touchpad flat, so it can effectively protect Planar antenna and easy to install and use the touch panel.

The amount of the above-mentioned 峨 wire is less than 1mm, to avoid the plane antenna to electromagnetic interference; the thickness of the planar antenna is about 0.02mm to 〇. 5mm, and j material is selected from copper, nickel, niobium or alloys of the foregoing materials, but the implementation range is not limited to the above materials, and each conductivity (four) is _. Since the planar antenna is disposed on the bottom surface of the color frame, the flatness and the first nature of the touchpad can be maintained and the space occupied by the antenna can be effectively saved, and the _ color border is such that the conductivity can be avoided. The no-sharp performance of the antenna is blocked or interfered by the screen 5 M425335; and the planar antenna is disposed in the recessed area of the substrate, so that the antenna has the same south degree as the touch sensing and the sensing wire, thus forming a flat touch The bottom of the board prevents the raised planar antenna from being scratched and allows the touchpad to be placed flat in front of the display to avoid optical interference. This will further clarify other functions and technical features of the present work, which will be realized by those skilled in the art after reading the description in the text.
