    • The present invention relates to a reconfiguration meta material antenna capable of adjusting polarization and frequency. The reconfiguration meta material antenna according to the present invention includes: a substrate having a dielectric reputation structure; a first patch which is formed in a circular shape on the lower surface of the substrate; a second patch which includes a circular patch formed on the upper surface of the substrate and at least one strip patch which is formed to have a constant width along the outer periphery of the circular patch, wherein the circular patch and at least the strip patch are connected via at least one diode. Therefore, according to the present invention, the reconfiguration meta material antenna is easier to miniaturize than a conventional circular polarized antenna by using a meta material and can provide various antennas functions with a single antenna by adjusting polarization and frequency.
