Abstract:

This paper presents a wideband planar microstrip antenna with metamaterial unit cell at 3.5 GHz for mid band frequency 5G applications. The planar microstrip antenna is designed with square patch and two longitude slots at 3.5 GHz. The metamaterial unit cell is designed individually based on split ring resonator (left-handed metamaterial) SRR LHM type. Then both structures are integrated together. The metamaterial is placed on the ground plane of the planar antenna. That will increase the bandwidth accordingly. The proposed metamaterial antenna is simulated and optimized using CST software. A good return loss of greater than 10 dB and an impedance bandwidth of 1.04 GHz are obtained. This metamaterial antenna is a good candidate for mid band frequency for 5G applications.
