Vertical complementary fractal antenna
First Claim
Patent Images
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 corresponding to the first fractal structure, with the area of the second fractal structure being no less than the area of the first fractal structure.

Abstract
A vertical complementary fractal antenna is provided, which includes a first fractal structure and a second fractal structure. The first fractal structure is defined as a superposition over at least one iteration of a motif, while the second fractal structure has a pattern complementary to that of the first fractal structure. Thus, the antenna may effectively increase bandwidth.
