Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a PCB-based 4G antenna. Background Technology

[0002] A PCB (Printed Circuit Board) is one of the essential basic components of the electronics industry. It replaces the chassis of traditional electronic components and enables the interconnection between them. Using an insulating board as the substrate, conductive lines are formed through an etching process, making circuit design more efficient and reliable.

[0003] An antenna is a component in wireless equipment that transmits or receives electromagnetic waves. 4G antennas are specifically designed for the transmission of 4G LTE network signals and are indispensable in scenarios such as mobile phones, routers, and monitoring equipment. Their core function is to convert electrical signals into electromagnetic waves, ensuring a stable 4G network connection.

[0004] In current daily life applications, 4G antennas are widely used in various application scenarios such as automobiles, mobile phones, routers, monitoring equipment, and short-range intercoms. However, the most common method is to use an external car antenna. This method inevitably has the disadvantages of large size and high cost. Moreover, the external antenna method is also relatively troublesome and cannot meet people's needs in many application scenarios. Utility Model Content
