Abstract
The invention relates to the field of wireless communication technology, and provides electronic equipment. The electronic equipment comprises a near-field communication antenna and a metal housing, wherein the near-field communication antenna and the metal housing are arranged adjacently. The near-field communication antenna is an annular coil antenna on which a plurality of coils continuously wind. A hollow area is formed in the coil antenna. A slit is arranged on the metal housing. The projection of the slit on the metal housing on the coil antenna covers and bestrides an annular area which is formed between an inner antenna and an outer antenna in the coil antenna. Through arranging the slit on the metal housing, in outward electromagnetic radiation of the near-field communication antenna, current which is generated by magnetic field change in the metal housing cannot form a loop, thereby preventing eddy current. Therefore the metal housing cannot shield the electromagnetic signal of the antenna. The signal which is generated by the near-field communication antenna is radiated out from the slit, thereby performing a function of recovering communication.
