Abstract
A left-handed resonator according to the present invention includes: a series body in which an inductor component and a capacitor component are connected in series; and a parallel body in which an inductor component and a capacitor component are connected in parallel, wherein one end of the series body and one end of the parallel body are connected, the other end of the parallel body is grounded, and the other end of the series body is grounded. With this configuration, a −1-order mode is excited using only one unit cell including the series body and the parallel body, so that dimensions of the left-handed resonator can be miniaturized.
