A Compact and Extremely Stiffness CPW-Fed Metal-Only Patch Antenna Array for Unlimited Lifetime 2U CubeSat Mission Capabilities

This article is designed to help with the construction of an integrated small-size antenna system for 2U CubeSats. Dipole antennas necessitate deployable subsystems for 2U CubeSats, which have a limited space margin for redundant components inside the box, making the antenna deployment subsystem a single point of failure. In this letter, a 50 Ω coplanar waveguide strip line supplied the integrated metallic antenna array. The goal of this research is to create a high-strength 2U CubeSat body integrated metallic patch antenna capable of performing for infinite lifespan CubeSat flights while using little power. Due to the Quasi Newtonian Method’s optimization of the entire antenna architecture, the antenna has a high return loss, a peak gain of almost 17.0 dBi, and an incredibly broad impedance bandwidth centered on the working frequency of 12.05 GHz. In addition, the proposed metallic antenna array is cheap, lightweight, and has a very stiff construction for usage in space applications. These achievements enable us to continue pursuing long-term, low-cost, high-altitude satellite missions using 2U CubeSat designs at low power consumption.
