Design of graphene patch array antenna for 5G applications

Abstract

The array antenna is a good choice for 5G communication owing to the capability of acting in millimeter-wave range with having high gain and wide bandwidth. This paper presents the design and simulated results of a graphene array antenna for 5G wireless communication using CST microwave studio. The array is designed and compared with single patch antenna and optimized for observing an increase in directivity. Maximum directivity of 20.35dB is obtained by implementing four by two (4×2) array of eight patches as compared to 8.87 dB for single patch at 60 GHz center frequency.
