Description

Technical Field

[0001] This application relates to the field of router antennas, and more particularly to a multi-band stamped structure antenna. Background Technology

[0002] With the rapid development of wireless communication technology, wireless communication has been implemented in public places, hotels, and homes. However, the requirements for public Wi-Fi usage are becoming increasingly stringent. Users need consistent Wi-Fi signal strength in all corners of office buildings, shopping malls, and homes, without affecting network speed or user experience, and without needing to reconnect due to changes in network routers. This wireless communication is achieved through wireless router terminals. However, the coverage area of ​​wireless router terminals is limited, leaving many dead zones uncovered, such as underground parking lots, restrooms, and storage rooms. Furthermore, the farther away from the wireless router terminal, the weaker the signal received by mobile devices (such as mobile phones and computers), resulting in slower internet speeds and a poorer user experience.

[0003] To cover all the blank areas and dead zones of all models, WIFI extenders have emerged. WIFI extenders can expand the coverage range of the wireless signal of a wireless router terminal, and at the same time enhance the wireless signal, making mobile terminals access the Internet faster.

[0004] Antennas are components in systems such as wireless communication, broadcasting, satellite communication, navigation, and cordless phones that radiate and receive electromagnetic wave energy. They are energy converters that transform guided and radiated waves, and their performance plays a crucial role in the entire system. With the rapid development of modern wireless communication, especially the widespread application of WLAN (Wireless Local Area Network), LTE (Long Term Evolution), and CDMA (Code Division Multiple Access), the performance requirements for antennas are becoming increasingly stringent.

[0005] In actual production, in order to increase more signal channels and improve the structural design of antennas, and according to the signal speed and channel requirements, a certain number of antennas are integrated into a router or amplifier.

[0006] In existing technologies, when integrating a number of antennas into a router or amplifier, the antenna design is based on a separate wiring layout for each antenna. This wiring layout typically involves laser engraving and plating on a plastic bracket, with LDS antennas being one example. First, the antenna pattern is laser-engraved on the plastic bracket, then copper and nickel are plated. To ensure the stability of the plating and contact effect, gold plating is required at the contact points with the springs, such as the antenna feed point area. Currently, the common practice is to plating the entire laser-engraved area with gold. However, for products with large plating areas, large-area gold plating is very costly. Furthermore, the laser engraving and plating process is quite complex and requires high-level technical skills. Additionally, the parameters of the plastic mold can affect the plating performance of the wiring, leading to poor plating and impacting performance. Summary of the Invention
