Abstract

This work presents a novel ring-shaped Vivaldi ultra-wideband (UWB) MIMO antenna designed for omnidirectional coverage. The antenna features a low profile, reduced cross-polarization, and full UWB spectrum coverage from 3.1 GHz to 10.6 GHz, making it ideal for commercial applications. The design utilizes a dual-layer structure on a low-loss dielectric substrate, effectively minimizing mutual coupling and optimizing signal distribution. Simulation results demonstrate the antenna's superior performance, underscoring its potential for advanced wideband communication systems.
