MULTIBAND ANTENNA USING A METAMATERIAL, AND COMMUNICATION APPARATUS INCLUDING SAME

摘要

The present invention relates to a multiband antenna using a metamaterial, and to a communication apparatus including same. The present invention includes one or more metamaterial units having metamaterial properties, and, by adding a capacitive coupling device between a radiating patch and a substrate and controlling the reactance component of the metamaterial unit, provides a smaller multiband antenna that can easily control a resonance frequency, as well as a communication apparatus including same. According to the present invention, by adding the capacitive coupling device between the radiating patch and the substrate of the antenna using a metamaterial and controlling a parallel capacitance existing between the radiating patch and the substrate, the parallel capacitance can be effectively controlled without modifying the substrate.
