[0027] Referring to Figure 1 And Figure 2 The utility model provides a kind of double-frequency WiFi antenna suitable for metal ring, including substrate 1 and the antenna main body being set on the substrate 1, the antenna main body includes electrically interconnected 2.4G branch 2, 5G branch 3 and tuning branch 4, the 5G branch 3 and the tuning branch 4 are adjacent interval arrangement, the 2.4G branch 2 is connected with the 5G branch 3, the tuning branch 4 respectively, the 2.4G branch 2, the 5G branch 3 and the tuning branch 4 are enclosed and form tuning groove 7.By adjusting 2.4G branch 2, 5G branch 3, tuning branch 4 and tuning groove 7, the transmission gain of alternating current signal is changed, finally by antenna conversion electromagnetic wave radiation, wherein, 5G branch 3 is used to generate ultra-high frequency 5G WiFi resonance, 2.4G branch 2 is used to form high frequency 2.4G WiFi resonance, tuning branch 4 can be used to correct 5G WiFi resonance frequency band, tuning groove 7 can be used to correct 5G WiFi resonance frequency band and 2.4G WiFi resonance frequency band, improve the anti-interference performance of antenna, the antenna of the case is placed in metal ring, still can keep good radiation performance.

[0028] Specifically, the current flows to the 5G branch 3 to generate a super-high-frequency 5G WiFi resonance, and the resonance frequency band is 5150-5850 MHz. The 2.4G branch 2 is coupled with the environment to offset, and the offset is to a lower frequency to form a high-frequency 2.4G WiFi resonance, and the resonance frequency band is 2400-2500 MHz. The tuning slot 7 can correct the offset resonance of the 5G WiFi within a certain distance to the required 5G WiFi resonance frequency band, i.e. 5150-5850 MHz, and the correction range is within 500 MHz, i.e. the resonance frequency band without tuning is 5650-6350 MHz.

In general, the 5G WiFi resonance is realized by the 5G branch 3, the tuning branch 4, and the tuning slot 7, and the resonance frequency band is 5150-5850 MHz.

[0029] Specifically, in the high-frequency 2.4G WiFi resonance, the 2.4G branch 2 is coupled with the environment to offset, and the offset length depends on the length of the environment area corresponding to the 2.4G branch 2. When the interval width between the environment areas corresponding to the 2.4G branch 2 is 3 mm, the best effect can be achieved, which does not affect the loss of the environment to the antenna body, and can utilize the environment to generate an additional frequency offset correction effect and the bandwidth correction effect of the tuning slot 7. The longer the length of the tuning slot 7, the wider the resonance width. Only the bandwidth between 2400-2500 MHz needs to be corrected. The high-frequency 2.4G WiFi resonance is realized by the 2.4G branch 2, the antenna body, and the tuning slot 7, and the resonance range is 2400-2500 MHz.
