Description

Technical Field

[0001] The utility model relates to the field of antennas, in particular to a WiFi external antenna. Background Art

[0002] In the existing market, most of the external wireless communication technologies that use ABS rubber sleeves are routers and set-top box WIFI antennas. As we enter the era of the Internet of Everything, the Internet of Everything is defined as the combination of people, processes, data and things to make network connections more relevant and valuable. The Internet of Everything transforms information into action, creates new functions for enterprises, individuals and countries, and brings richer experiences and unprecedented economic development opportunities. The external antenna is an antenna installed on the router. In order to meet the needs of modern communication equipment, the research and development of antennas is mainly carried out in several aspects, namely, size reduction, broadband and multi-band operation, and intelligent directional pattern control. With the improvement of the integration of electronic equipment, the size of communication equipment is getting smaller and smaller. At this time, the antenna is too large for the entire device, which requires the antenna to reduce its own size. However, it is a difficult task to reduce the size of the antenna without significantly affecting the gain and efficiency of the antenna.

[0003] Existing WiFi external antennas also have the following defects: the overall structure has many parts and components, and the structure is complex. The antenna is usually composed of a shell, a cavity, a main control circuit board, a vibrator, a spring for achieving fixed connection, a wire for transmission, a base for fixing the main control circuit board, glue or other adhesives for fixing the base inside the shell, and a vibrator feeding foot and other components. The main control circuit board is fixed to the base by welding, and the base is directly fixed to the inside of the shell by glue or other adhesives. The vibrator is fixed to the main control circuit board by welding, and one end of the spring is connected to the inside of the shell, and the spring is connected to the inside of the shell. The other end of the spring is connected to the vibrator to fix the vibrator. The wires used for transmission are wound around the inside of the shell in a disorderly manner. The vibrator feeding feet connect the wires, the vibrator, and the main control circuit board. However, this spring-fixed vibrator has poor fixation. The periphery of the vibrator is hollowed out, and the vibrator extends to the outside of the main control circuit board. When the shell is collided, dropped, or hit by external force, the vibrator and the main control circuit board will separate. The fixation of adhesives such as glue is unstable, which can easily make the main control circuit board loose, thereby causing the main control circuit board and the vibrator to shake inside the shell, resulting in the possibility of performance degradation or damage to the vibrator.
