AI Technical Summary

Technical Problem

The increased screen-to-body ratio of full-screen phones leads to poor radiation performance of dual-band Wi-Fi antennas.

Method used

Design a small dual-band WiFi antenna with a feed point, a feed location, a first stub, and a second stub. The first stub is set parallel to the first coupling slot, and the second stub is connected to the feed location. The free ends of the first and second stubs extend in opposite directions to avoid frequency interference. The length of the coupling slot is adjusted to tune the dual-band WiFi.

Benefits of technology

The spoofing performance of the dual-band WiFi antenna in a limited space has been improved, the spoofing effect in a limited space has been resolved, the mutual interference between the 2.4G WiFi frequency and the 5G WiFi frequency has been avoided, the impact on signal radiation efficiency has been reduced, and the radiation performance has been improved.
