AI Technical Summary
Existing monopole antenna modules typically only cover a single frequency band, making it difficult to meet the needs of multi-band communication. Furthermore, the lack of insulation design leads to direct contact between the antenna assembly and the metal housing or other conductive components, which can easily cause electrical short circuits and signal interference.
Design a multi-band monopole antenna module, including a housing, two antenna assemblies and an insulating component. The antenna assemblies can be tuned to different frequency bands through independent design. The insulating component is placed below the antenna assemblies to isolate the metal parts. The antenna vibrator can be quickly installed and removed through a locking mechanism. Sealing gaskets and buckles are used to improve the insulation and stability of the components.
It expands the frequency coverage of the antenna, enhances electrical safety, reduces signal interference, and improves maintenance and production efficiency.
