Abstract :
This paper aims at describing the effect of a novel metamaterial inspired structure (Complementary Split Ring Resonator) on miniaturization of a Microstrip patch antenna. The CSRR possesses SNG property (-ε). A hexagonal microstrip patch antenna loaded with CSRR in the ground plane is studied under two different cases. The first case is loaded with an open ended CSRR and the second case is with a closed CSRR. A 20mm×20mm×1.6mm hexagonal patch antenna resonated at 8.3 GHz. Inclusion of the O-CSRR made the patch to resonate at 7.7GHz and the modified structure brought down the frequency to 5.6GHz, making it suitable for WLAN (IEEE 802.11a) application. The maximum dimension of the patch used in this work is 0.186λ. Antenna miniaturization of 57% is inferred from the simulation results. Bandwidth, return loss and radiation efficiencies are also discussed in this paper.
