Small antenna using SRR structure in wireless communication system and method for manufacturing the same

A method for manufacturing a small antenna using an SRR structure in a wireless communication system, comprising:

• forming a first radiation unit with a predetermined ring shape by patterning a metallic conductor over a dielectric substrate formed of a predetermined dielectric medium;
• forming a second radiation unit with a predetermined ring shape by patterning a metallic conductor under the dielectric substrate;
• forming a via through the dielectric substrate such that the via connects the first and second radiation units;
• forming a feed unit configured to feed a signal to the first radiation unit and a transfer line unit configured to transfer the signal to the feed unit over the dielectric substrate;
• forming a ground unit under the dielectric substrate, the ground unit configured to ground the first and second radiation units;
• and
• forming a metal line unit under the dielectric substrate, the metal line unit configured to connect the second radiation unit and the ground unit,
• wherein when the signal is fed to the first radiation unit by the feed unit, first and second capacitances are generated to accomplish impedance matching.
