Method and apparatus for improving performance of antenna

The invention discloses a method and an apparatus for improving performance of an antenna. A floor is mounted at the bottom of an antenna radiation apparatus; the floor is connected with the ground of the antenna radiation apparatus; at least one introduction vibrator is arranged on the floor; and the mutual distances between the multiple introduction vibrators, and the distances between the introduction vibrators and a vibrator of the radiation apparatus are arranged periodically or non-periodically. By introducing the floor to the bottom of the antenna radiation apparatus, the dimension of the antenna ground is enlarged, the reflective effect of the ground plane is improved, and the performance of the antenna can be improved to a certain degree; by increasing the introduction vibrators, the introduction vibrators have influence on the current of the vibrator of the antenna radiation apparatus, so that the current distribution of the vibrator of the antenna radiation apparatus can be changed by regulating th
