This paper describes the design of an antenna array and its integration with a beamforming network that operates at
2.6 GHz and uses circular microstrip patch antennas and their arrays over a frequency range of 2–3 GHz. This design is
implemented on a substrate (RT5880) with a dielectric constant (ε = 2.2), loss tangent (tanδ = 0.0009), and thickness (h =
0.0813 cm). The microstrip antenna's dimensions were calculated and subsequently determined through simulations. The
Antenna Feeding Network with Beamforming exceeds Single and Array Antennas, providing superior directional radiation. With
an amazing 9.02 dBi gain, 32.6 dBi front-to-back ratio, and 67% Total radiation efficiency at 2.6 GHz. A comparison and
observation are made between the effectiveness of the designs and the suggested techniques. CST Microwave Studio is a fullwave electromagnetic simulation software program for design and analysis.
