Abstract:

This paper presents a wideband planar microstrip antenna based on split ring resonator left-handed metamaterial (SRR-LHM) type at 3.5 GHz frequency for mid-band 5G mobile applications. The need to design a wideband antenna with good gain realising the proposed lower band spectrum for 5G technology is urgently demanded. To meet the requirements, microstrip technology and metamaterial are proposed. Firstly, the microstrip antenna is designed with a square patch and two longitude slots at 3.5 GHz. The metamaterial unit cell is designed individually based on the split ring resonator (left-handed metamaterial) SRR LHM type and then integrated with the developed antenna at the same band. The metamaterial is placed on the ground plane of the microstrip antenna. That will increase the bandwidth accordingly. The proposed metamaterial antenna is simulated and optimised using CST software. A good return loss of greater than 10 dB and impedance bandwidth of 1.04 GHz is obtained. This metamaterial antenna is a good candidate for mid-band 5G applications.
