AI Technical Summary

Technical Problem

Existing PCB antennas are difficult to support the 2.4GHz, 5GHz and 6GHz frequency bands, which cannot meet the requirements of WiFi 7 wireless network cards, and are also not suitable for the miniaturization design of wireless network cards.

Method used

Design an antenna structure including grounding traces, radiating traces, and gain traces. Through the coupling of the grounding body, grounding arm, radiating body, and connecting traces, achieve coverage of the 2.4GHz, 5GHz, and 6GHz frequency bands, and control the length and width of the antenna to meet the miniaturization requirements of wireless network cards.

Benefits of technology

It supports 2.4GHz, 5GHz and 6GHz frequency bands to meet the requirements of WiFi 7 wireless network cards, while the antenna length and width are controlled at 104±1mm and 8.5±0.5mm respectively, realizing the miniaturization of wireless network cards.
