    • Disclosed are a broadband antenna using metamaterials and a communication device including same. The broadband antenna using metamaterials according to an embodiment of the present invention comprises: a radiating patch which is a transmission line having right-handed (RH) characteristics in a composite right/left handed transmission line (CRLH-TL) structure, and is particularly patterned according to a resonating frequency to act as a radiating element of the antenna; a feed line connected to one end of the radiating path for supplying power to the radiating patch; a ground line connected to the other end of the radiating path for grounding the radiating patch; and a ferritic helical loading unit which is formed on the ground line and acts as a first parallel inductor having left-handed (LH) characteristics in the CRLH-TL structure. Therefore, the bandwidth of the metamaterial antenna can be extended.

    • 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.
