<p>This small-sized antenna that operates in a plurality of frequency bands comprises: a first conductor plane in which a first split-ring resonator and a second split-ring resonator having different resonance frequencies are formed; and a power feed line including a first branch line, a second branch line, and a branch part. Each split-ring resonator includes: a conductor region along the opening edge of an opening formed in the first conductor plane; and a splitting part that splits a portion of the conductor region. One end of the first branch line is connected to the first split-ring resonator, and the other end crosses the conductor region and extends up to the branch part. One end of the second branch line is connected to the second split-ring resonator, and the other end crosses the conductor region and extends up to the branch part.</p> |
