Human Face-shaped Planar Antenna for 5G sub-6 GHz Application

This paper presents a planar antenna for the fifth generation (5G) sub-6 GHz communication application. The layout of the proposed antenna consists of a human face-shaped radiating element and defected ground, and is fed by a microstrip line. The simulation and measured results confirmed the radiation element matched correctly with the ground, which helped the antenna to work over 3.25 to 5.05 GHz (43.4%). The antenna also has moderate gain, good efficiency, and revealed symmetric radiation behavior, making it a potential contender for 5G wireless communication.
