Effect of complementary triangular split ring resonator on microstrip patch antenna

In this paper, a new complementary triangular split ring resonator (CTSRR) is proposed and the impact of CTSRR on conventional patch antenna is investigated at 2.44 GHz for WLAN applications. The electromagnetic behavior of CTSRR, as well as their equivalent circuit is developed and explained. The demonstrated theoretical approaches result in a meaningful improvement than in comparison to conventional patch antenna. The parametric studies are completed in this work with the different orientation pattern of CTSRR structure. This is exposed that with the increment of CTSRR on patch, antenna performances improve, but resonance frequency shifts toward lower frequency region.
