Claim 15:
16. A terminal, comprising:
a built-in antenna, wherein the built-in antenna comprises a radiating element;
a reflecting element; and
a radio frequency coaxial cable;
wherein the radiating element and the reflecting element are located on a same plane, and the radiating element is connected to the radio frequency coaxial cable;
wherein the radiating element comprises an upper radiation arm, a lower radiation arm, and a balun, wherein the upper radiation arm and the lower radiation arm form an L-shaped longitudinal cabling structure or a local snake-shaped structure, and wherein the upper radiation arm and the lower radiation arm are connected to the balun;
wherein the reflecting element is of a comb structure, the comb structure comprises at least two comb teeth, sizes of all the comb teeth are the same, intervals between every two adjacent comb teeth are the same, and a comb-like opening face of the reflecting element is opposite to the radiating element;
wherein the radio frequency coaxial cable is configured to receive a radio frequency signal;
wherein the radiating element is configured to radiate the radio frequency signal, to obtain a first radiation signal and a second radiation signal, and the first radiation signal and the second radiation signal have different directions;
wherein the first radiation signal is reflected by the at least two comb teeth, to obtain a reflection signal, and a direction of the reflection signal is the same as the direction of the second radiation signal; and
wherein the second radiation signal is coherently superimposed with the reflection signal, to output a superimposed signal.
