Disclosed are an antenna and a terminal. The antenna comprises a first antenna stub, a ground stub, a second antenna stub, and a first feed. The first antenna stub is printed on a first surface of a circuit board, and comprises first sub-stubs. The ground stub is printed on the first surface and comprises ground sub-stubs. The first sub-stubs and the ground sub-stubs are arranged in a staggered manner to form slots. The first antenna stub and the ground stub are coupled to each other by means of the slots. The second antenna stub is printed on a second surface of the circuit board, and the second surface and the first surface are two opposite surfaces of the circuit board. The first feed is electrically connected to the first antenna stub. The second antenna stub is electrically connected to a metal through-hole in the circuit board. The metal through-hole is electrically connected to the first feed. The first antenna stub, the ground stub and the first feed form a first antenna, so as to generate a first resonant frequency. The first antenna stub, the second antenna stub and the first feed form a second antenna, so as to generate a second resonant frequency. |
