Miniaturization of Square Patch Antenna using Complementary Split Ring Resonators
In this paper, a novel compact micro strip antenna, designed on FR4 substrate, is proposed. Here, a compact square patch antenna is designed in such a way that the radiating patch is loaded by a layer of metal between the patch and the ground which makes the antenna operate at a lower frequency. The antenna design is optimized to obtain a resonant frequency of 2.45GHz. Miniaturization of the antenna is obtained by using meta-material based structures inscribed on the metal layer. The meta-material structure used here is a square-shaped complementary split ring resonator (CSRR). On varying the number and size of inclusions, high levels of miniaturization are observed.
