Correct interpretation of the status of LDS antenna technology on 4G mobile phones
The LDS antenna technology is a laser direct structuring technology that uses a computer to control the movement of the laser according to the trajectory of the conductive pattern, and projects the laser onto the molded three-dimensional plastic device to activate the circuit pattern in a few seconds. Simply put (for the design and production of mobile phone antennas), on the molded plastic support, laser laser technology is used to directly form a metal antenna pattern on the support. Such a technique can directly laser the antenna to the outer casing of the mobile phone. Compared with traditional mobile phone antenna technology, the advantages of LDS antenna technology have emerged. Firstly, the antenna produced is stable in performance, good in consistency and high in precision. The laser system is durable and less maintenance. It is suitable for 7X24 uninterrupted production, low failure rate, and can fully utilize the three-dimensional structure of the bracket to form the antenna pattern. Secondly, the manufacturing process is short, no circuit graphics mold is required, and environmental protection is required. For the antenna RF, it is sufficient to give a three-dimensional CAD drawing, eliminating the need for repeated communication with the ME and mold modify. Again, because the antenna is laser-mounted on the phone case, it avoids the interference of the internal components of the mobile phone, ensures the signal of the mobile phone, and also enhances the utilization of the space of the mobile phone, so that the body of the smart phone can reach a certain degree of slimness. . As the industry continues to improve with technology and cost, terminal manufacturers will be more accepting LDS antennas. At the same time, with the diversification of functions of smart phones, the development of various wireless applications has made more and more wireless transmission devices in mobile phones, and the number of corresponding antennas will inevitably increase, which is a good advantage for the antenna industry. In other areas, the company does not rule out the involvement of car antennas through mergers and acquisitions, and the field of wearable devices is cut from the antenna. Due to the high frequency requirements of the 4G mobile phone, the 3D design of the LDS antenna is more conducive to achieving RF performance. The new LDS antenna has begun to become a new direction for antenna development under the trend of multi-frequency multi-mode and terminal thinning. In order to realize 4G communication, multi-frequency multi-mode and antenna shape are required to be three-dimensional. It is necessary to realize computerized automation design, and at the same time, the precision of manufacturing is becoming higher and higher. The early FPC, shrapnel and other manual design, test and manufacturing modes Not applicable, in the automatic design and manufacturing, the highest accuracy of 3D manufacturing is LDS technology; wearable devices need to be equipped with Bluetooth, NFC, WIFI and other antennas, and some will also be equipped with 4G modules, which are more antennas in smaller space (surface) The integration requirements are higher than those of traditional antennas such as mobile phones, shrapnel or FPC. LDS is a better choice; in addition, the main implementation process of smart car antennas is also LDS antennas. Multi-domain antenna trends are pointing to LDS, and the demand for this technology has entered an explosive growth period. In recent years, with the rise of mobile payment, NFC has also become a trend. China Telecom and China Mobile require all models of 3G/4G mobile phones to be gradually equipped with NFC functions. China Unicom (600050, shares it) requires more than 2,000 yuan models to have all NFC functions ("basic" is mainly considering the iPhone). In 2014, the MTPS platform was completed, and TSM, a company of 7 institutions including China Construction Bank, China CITIC Bank, China Everbright Bank, China UnionPay, and China Mobile, has been installed at the system level. Shanghai Metro supports NFC mobile phones, and Beijing bus, subway and convenience stores have fully supported NFC mobile phones. The large-scale promotion conditions of NFC have gradually matured. The process of integrating NFC with LDS is integrated into the phone case. Mr. Wu, an industry person, told us that this is not a difficult task. This is completely feasible in terms of technology and technology. Because NFC is a near-field wireless communication technology, as long as the RFID is adjusted to the frequency band of 13.56MHz by technical means, the perfect integration of the two can be achieved. However, no one on the market has this product yet. I believe that in the near future, there will definitely be manufacturers to take the lead.
