TERMINAL ANTENNA

Embodiments of this application relate to the field of antennas, and provide a terminal antenna, which can improve a radiation efficiency of a terminal antenna. The terminal antenna includes n radiators. The n radiators include a first radiator, a second radiator, and a third radiator. Lengths of the first radiator, the second radiator, and the third radiator form a descending arithmetic progression. The first radiator, the second radiator, and the third radiator are arranged in sequence to form two gaps. A coupling capacitance formed by the first radiator and the second radiator through the corresponding gap is greater than a coupling capacitance formed by the second radiator and the third radiator through the corresponding gap. The first radiator, the second radiator, and the third radiator are any three of the n radiators distributed in sequence. One end of the terminal antenna is connected to a ground point, and the other end thereof is connected to a feed point. A radiator connected to the ground point is a shortest one of the n radiators, and a radiator connected to the feed point is a longest one of the n radiators.
