Wi-Fi, also called "action Hot Point" in Chinese, is a brand authentication of products by the brand of Wi-Fi alliance manufacturers, and is a wireless local area network technology established in the IEEE 802.11 standard.

At present, almost all terminal equipment such as smart phones, tablet computers and notebook computers support Wi-Fi internet surfing, and the Wi-Fi internet surfing is a wireless network transmission technology which is used most widely at present. In fact, the wired network signal is converted into a wireless signal, and a wireless router is used for receiving related computers, mobile phones, panels and the like supporting the technology. The popularization of Wi-Fi provides convenience for life of people, friends and family can communicate with each other through the internet, send short messages and share files, and people can watch TV and movies through the internet.

The terminal equipment in the related art comprises two Wi-Fi antenna structure schemes, namely a single Wi-Fi antenna scheme and a double Wi-Fi antenna scheme.

In a conventional single Wi-Fi antenna scheme, in a game scene of a horizontal screen, a Wi-Fi antenna is easily shielded by hands, so that the amplitude reduction of OTA (namely omnidirectional transmitting power and omnidirectional receiving sensitivity, which are both related to antenna efficiency) usually reaches 6-10dB, and the Wi-Fi communication quality of terminal equipment is seriously influenced.
