Application Spotlight: PDS Antenna Solution Revolutionizes Consumer Electronics​ Process

To remain competitive in modern consumer electronics, antenna components must be miniaturized and lightweight while ensuring signal performance and cost-effectiveness. A leading consumer electronics manufacturer approached TK Precision with a request: adopt PDS antenna manufacturing technology, provide solutions, iteratively upgrade its existing coil antenna solution, and adjust the space to provide a larger storage location for the battery to enhance product endurance. The new PDS antenna combines a shell structure with an one-piece production design and rigorous performance testing. It is ahead of the original coil antenna in all indicators such as S11/Gain/Efficiency, and has doubled the communication distance in actual verification tests, which is recognized by customers.

Solution

TK Precision's solution is its innovative Printing Direct Structuring (PDS) antenna, which uses high-precision pad printing technology to replace the original coil antenna structure. On the basis of not changing the appearance of the shell, through scientific design, it makes full use of the internal space of the shell to expand the signal coverage, thereby increasing the communication distance, while reducing production time, reducing processing costs, reducing product weight, and providing convenience for battery expansion, thereby increasing the battery life. Customer tests demonstrate that, at equivalent power levels, the device's obstacle-free signal coverage distance extends from 20 meters to 39 meters, with communication efficiency increasing by as high as 95%.

Results

PDS Antenna solution elevated operational flexibility and delivered significant performance gains for the client:

• Breakthrough innovation: PDS printing technology provides better high-frequency electromagnetic characteristics than the original coil.
• Lightweight structure: Flexible integrated substrate replaces metal coil components, reducing the overall weight of the product.
• Cost optimization: Automated pad printing technology minimizes material consumption and eliminates welding steps, thereby simplifying the production process.
• Battery life optimization: PDS antenna does not occupy the original antenna space, expands battery capacity, and has longer standby time.

• Process diversity: PDS antenna technology provides new options for devices such as consumer electronics, IoT terminals and portable products, accurately adapting to the signal transmission needs of wearable devices, smart homes and consumer electronics, and providing cross-category antenna solutions.
• Core technology innovation: The groundbreaking PDS silver paste printing process, relying on numerous patented technologies, breaks through the mechanical limitations of traditional coils through high-precision pad printing techniques, and achieves better electromagnetic field signal coverage.
• Performance breakthrough: Two-dimensional advancement (efficiency + range): After laboratory and field comparison tests, under the same test conditions, the PDS antenna has achieved significant improvements in efficiency and signal coverage.
