BROADBAND CIRCULARLY-POLARIZED SPIDRON FRACTAL ANTENNA

摘要

PURPOSE: A broadband circularly-polarized spidron fractal antenna is provided to implement a broadband property without a multilayer board by forming a spidron fractal shaped slot on a ground surface. CONSTITUTION: A ground surface(21) is formed on the upper side of a dielectric substrate(24). A spidron fractal shaped slot is formed on a ground surface. A microstrip line(25) is formed on the lower side of the dielectric substrate. The microstrip line feeds the current to the spidron fractional shaped slot through the dielectric substrate. An SMA connector(23) is attached to the dielectric substrate and is connected to the microstrip line and the ground surface.
