Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment, specifically a 5G antenna with a PCBA design body and an FPC array. Background Art

[0002] In the design of electronic products, single PCBA (printed circuit board assembly) or single FPC (flexible printed circuit board) solutions are more common. However, single PCBA may not meet the requirements of certain specific application scenarios in terms of frequency coverage. For example, in scenarios requiring ultra-wide bandwidth or high-frequency transmission, a single PCBA may not provide sufficient performance support. Although FPC has many advantages, in certain application scenarios, such as those that need to withstand large mechanical stress or high-temperature environments, a single FPC may not provide sufficient performance support. Therefore, we need to propose a 5G antenna that uses a PCBA design with an FPC array attached. Utility Model Content

The use of multiple FPC arrays solves the frequency that cannot be met by the PCBA body, greatly reducing the cost of customer application products.
