Claim:
1. A method for designing an antenna device, the antenna device comprising: a plurality of structures, each structure including: a first one of the structures constitutes a first split ring resonator antenna which resonates at a first frequency, and a second one of the structures constitutes a second split ring resonator antenna which resonates at a second frequency; counter electrodes which are formed at a right angle while extending from the respective conductor layers at both ends of the first split ring portion and the second split ring portion inward toward a position where the opening is formed in such a manner as to sandwich the first split portion and the second split portion included in each of the first split ring resonator antenna and the second split ring resonator antenna, adjusting the antenna device in such a manner that an electrostatic capacitance between the counter electrodes of the first split ring resonator antenna is increased, as a length of a side portion of the first split ring resonator antenna where the first split portion and the second split portion are formed, and a length of a side of the first split ring resonator antenna facing the side are shortened so as to approximate a value of reflectance representing a ratio of output power with respect to input power of a signal of a second frequency to be input to the first split ring resonator antenna to zero when the input signal of the second frequency is reflected on the first split ring resonator antenna.
