ANTENNA DEVICE AND TERMINAL

摘要

The embodiments of the present invention provide an antenna device and a terminal, relate to the field of communications, and can limit the lead direction of "ground" currents on the edges of the single board where the antenna is located. The antenna device includes: an antenna, a single board provided with the antenna, and also includes: a first area not covered with a metal layer and provided on the single board, wherein, a first edge of the single board is the longer one of the two edges of the single board, the two edges being close to the antenna; on the first edge, a point with a distance of λ/4 to the first current peak point on the first edge is the first base point; wherein, the first current peak point is the current peak point on the first edge closest to the feed point of the antenna, and λ is the working wavelength of the antenna; the first area not covered with a metal layer covers the first base point, and the maximum distance from the edge of the first area to the first edge of the single board is λ/4.
