Abstract
This paper presents a design of high gain wideband antenna with metasurface for sub-6 GHz applications. The antennas at sub-6 GHz have a narrow bandwidth and low gain with a narrower axial ratio (AR). Hence, antennas combined with metamaterials are proposed to overcome these issues. The proposed metasurface antenna is designed with the implementation of W-shape transmission lines within the vias. The proposed antenna with metasurface is simulated using CST software and then fabricated on the FR4 substrate with (er=4.4 and h=1.6 mm). The antenna performance achieved a wide bandwidth of 85% and operates at 2 GHz to 5 GHz. A compact size of 45% is achieved with a high gain of 7.12 dB. The proposed antenna is suitable to be used in future sub-6 GHz applications.
