PROBLEM TO BE SOLVED: To provide an antenna structure capable of suppressing a decrease in communication speed.SOLUTION: An antenna structure 10 includes: a substrate 1; a split ring resonator antenna 5 consisting of a split ring resonator 3 formed on the substrate 1 and composed of a conductor pattern supplied with a predetermined current, and an impedance characteristic adjustment pattern 4 formed on the substrate on the right or left side of the split ring resonator 3 side by side, and adjusting impedance characteristics of the split ring resonator 3; and a vertical conductor 6 stood at predetermined positions of blade-like parts 16 and 17 in right and left regions of the split ring resonator antenna 5. The split ring resonator antenna 5 resonates with predetermined current and current flowing to the blade-like part 16 is shunt to the vertical conductor 6 through the resonance.SELECTED DRAWING: Figure 1 |
