Abstract

The invention discloses an antenna applicable to a mobile terminal. The antenna comprises upper and lower printed boards; a monopole radiation unit is printed on the front of the lower printed board; the monopole radiation unit is electrically connected to a metal feeding point; clad copper at the back of the lower printed board is used as one part of a radiator of the antenna, and simultaneously used as a main floor of the antenna; a short-circuit radiation unit is printed on the front of the upper printed board; and the short-circuit radiation unit is connected to the clad copper at the back of the lower printed board. The monopole radiation unit and the short-circuit radiation unit are respectively printed on the upper and lower printed boards; therefore, resonance at different frequencies is generated; the antenna can work in multiple frequency bands; the occupation area of the antenna is effectively reduced; therefore, the structure of the antenna is compact; miniaturization of the antenna is easily realized; the monopole radiation unit in the lower layer is directly stimulated, and coupled to the short-circuit radiation unit in the upper layer; a distributed LC matching circuit can be realized; the capacitive reactance of an input port is increased; and the distributed inductive reactance characteristic is introduced.

Description

technical field [0001] The invention relates to the field of mobile terminal communication, in particular to an antenna applied to a mobile terminal.
