Microstrip antenna with fractal or prefractal perimeter

摘要

Microstrip antenna with fractal or prefractal perimeter.This invention relates to a microstrip antenna (1) whose perimeter (5) is fractal or prefractal. The antenna is formed by a flat surface made of conductive or superconductive material (2) whose perimeter is fractal or prefractal, placed in a parallel manner on a conductive or superconductive plane (3). Between both planes, there are one or several layers of dielectric material (4). The activation method of the antenna can be any of the conventional methods for this type of antenna, for example, by coaxial probe, slot, or electromagnetic coupling. These antennas, which are activated at certain frequencies greater than the frequency of the first resonance, have radiation diagrams whose maximum value is in the direction that is perpendicular to the plane that contains the antenna. At these frequencies, the directivity of the antenna is greater than that obtained at the frequency of the first resonance.IMAGE
