Abstract

This paper presents the design, simulation, and performance analysis of patch antenna arrays using uniform and nonuniform planar geometries for 5 GHz applications. Array configurations of 1×2, 2×2, and 4×4 are designed and evaluated their performances through simulation. The study investigates the impact of uniform spacing versus customized spacing and feedline design in nonuniform arrays. CST Studio Suite is used to analyze key performance parameters such as return loss (S11), bandwidth, VSWR, radiation and total efficiency, gain, directivity, and side lobe level (SLL). Results show that nonuniform designs offer superior S11 and bandwidth in several configurations and highlight trade-offs in efficiency and SLL. The work contributes in the modular feedline optimization applied across different array geometries (1×2, 2×2, and 4×4), enabling better impedance matching and bandwidth enhancement for compact 5 GHz systems.
