There is a need for two operating frequencies to provide continuous connectivity and support a variety of applications. These dual-band antennas work in either one frequency band at a time or both, simultaneously. They enhance wide bandwidth by providing large coverage areas. In this paper, a dual-band array antenna for 5G communication is proposed. Beamforming is achieved using the phased array technique, which enhances directivity and radiation pattern towards the main beam. The dual-band antenna is designed with two C-shaped slots and a circle etched on a rectangular shape to reduce power loss. The rectangular patch dimension is 57 mm x 36.5 mm and 0.524 mm in thickness. This antenna has a directional radiation pattern. Some of the parameters like directivity, gain, VSWR, reflection coefficient, and impedance are measured to check antenna performance. The operating frequencies are 2.15 GHz and 4.99 GHz with a return loss of -42.6021 dB and -25.432 dB, respectively. The VSWR obtained at both bands are 1.01 and 1.11, respectively. The substrate material used is Rogers RO4003C with a dielectric loss of 3.38.
