1. A vertical complementary fractal antenna, comprising:

  • a first fractal structure defined as a superposition over N iterations of a fundamental motif, with N≧

    1; and

    a second fractal structure complementary to the first fractal structure, with an area of the second fractal structure being no less than an area of the first fractal structure,wherein a shape of the first fractal structure is different from that of the second fractal structure, anda half portion of the first fractal structure and a half portion of the second fractal structure are used at a point of zero current of an antenna resonant frequency.
