Abstract

This project centers on the design and development of a bilateral microstrip MIMO antenna for S-band satellite communication, especially for mobile satellite services for high-speed communication, Earth observation data transmission, IoT networks in remote areas, military communication, and telemedicine. The microstrip MIMO antenna is designed with dimensions of 55.9 mm × 71.7 mm, operating at 2.8 GHz on low-cost FR-4 substrate with a thickness of 1.6mm is selected for its cost-effectiveness and availability. High Frequency Structural Simulator (HFSS) is used to design and simulate the antenna. Through simulation-based optimization, parameters like return loss, VSWR, radiation pattern, directivity, H-plane co-cross polarization, E-plane co-cross polarization, and gain are thoroughly analyzed to meet stringent requirements for satellite communication at 2.8 GHz.
