Wherein, the plastic cover surface 4 is provided with at least one slot 5, and at least one slot 5 is internally provided with a metal strip.
Specifically, a new resonance is generated between the metal strip and the antenna 1 by coupling. The antenna 1 is used for receiving and transmitting wireless signals by the terminal equipment, the main board 2 is an important component of the terminal equipment, and the main board 2 is used for installing various elements of the terminal equipment to form a circuit. After receiving the wireless signal, the antenna 1 transmits the signal to the main board 2 through the feeder line 3, and related elements on the main board 2 process the wireless signal, or a radio frequency transceiver module on the main board 2 transmits the signal to the antenna 1 through the feeder line, and the antenna 1 transmits the wireless signal. In order for the antenna to be able to better receive and transmit wireless signals, a gap of a preset width needs to be reserved between the antenna 1 and the motherboard 2. The plastic cover surface 4 plays an insulating role, so that the rear shell of the main board 2 is made of metal, and the receiving and transmitting of the wireless signals by the antenna 1 are not affected. When the rear shell of the main board 2 is made of metal, the plastic cover surface 4 needs to be arranged on the first gap, and the antenna 1 and the main board 2 are connected through the plastic cover surface 4, so that signals can enter the first gap between the antenna 1 and the main board 2 through the plastic cover surface, or the plastic cover surface is sent out from the first gap. Meanwhile, at least one slot 5 is arranged on the plastic cover surface 4, a metal strip is arranged in the slot 5, and new resonance is generated through coupling between the metal strip and the antenna 1, so that the bandwidth of high-frequency signals of the terminal equipment is enlarged.

As shown in fig. 2, the plastic cover surface 4 is not provided with a metal strip, so that the antenna generates a first return loss 21. When a slot 5 is arranged on the plastic cover surface 4, and a metal strip is arranged in the slot 5, new resonance is generated between the metal strip and the antenna 1 through coupling, namely, new second return loss 22 is generated on frequencies around the center frequency of the first return loss 21, so that the bandwidth of high-frequency signals of the terminal equipment is increased through the combination of the second return loss 22 and the first return loss 21 generated by the original antenna.
