The two ends of the enhancement section L2 are electrically connected to the base section L1 and the emission section L3 through a gain enhancer G, respectively, and the two gain enhancers G operate in the same frequency band and have the same gain power. The length of the enhancement section L2 is greater than the lengths of the base section L1 and the emission section L3, and the length of the enhancement section L2 is controlled at 30mm, so that the two gain boosters G resonate in the 5.8G band. When the router works, the network signals can be stabilized at a frequency band of 5.8G through resonance of the two gain intensifiers G, stronger signal strength can be output, and the attenuation rate is lower during long-distance transmission.
