Metamaterial Minkowski Fractal Antenna With Defective Ground Structure

Abstract

This paper explores two metamaterial fractal antenna (MFA), in which one has complete ground plane and other uses defective ground structure (DGS) with square split ring resonator (SSR) are designed for 5G applications. The radiating layer of both antennas based on first iteration of minkowski fractal structure with complimentary split ring resonator (CSSR). The proposed antennas are simulated using CST microwave studio. The MFA with complete ground plane/DGS is operating between 3.48GHz-3.52GHz and 3.3GHz-3.7GHz, respectively. Both antennas show an excellent gain of 5.1dB and 4.5dB, respectively. The results show that MFA with DGS structure has an excellent bandwidth improvement with good gain, which can be an ideal candidate for 5G application.
