Design and analysis of UWB microstrip antenna for 5G communications and military applications

This paper presents an ultra-wideband (UWB) microstrip antenna designed for military applications, capitalizing on the inherent advantages of millimeter-wave (mmWave) spectrum, particularly enhanced frequency reuse enabled by limited signal coverage and reduced interference. Fabricated on a compact Rogers RT/duroid 5880 substrate (8×15×0.4mm3), the antenna demonstrates a broad bandwidth, high radiation efficiency, and quasi-stable gain, fulfilling the demands of miniaturized wireless devices. The significant atmospheric attenuation at mmWave frequencies not only facilitates dense frequency reuse for improved network capacity but also enhances communication security through inherent resistance to long-range eavesdropping. These characteristics, combined with the antenna’s planar geometry, position it as a robust solution for different applications as: military applications, next-generation 5G infrastructure, secure IoT networks, and high-density urban deployments where spectral efficiency and signal integrity are paramount.
