However, one of the critical requirements for these systems in space missions is the presence of a reliable communication infrastructure. Particularly for CubeSat platforms operating under strict volume and mass constraints, the demand for high-gain, steerable, and bandwidth-optimized antenna solutions are steadily increasing. This study proposes an innovative solution based on a rotatable microstrip patch antenna design to address these needs. At the core of the proposed design lies a wideband microstrip patch antenna operating in the S and C bands, whose orientation can be controlled via a functional structural material capable of changing its shape in response to electrical stimulation (piezoelectric material). The design offers a lightweight, compact structure optimized for CubeSat applications. The design has been validated through simulation and is currently at the prototyping stage, with real-world measurements planned to be conducted in the near future. As a result, the proposed antenna system makes CubeSats more effective, flexible and reliable for complex space missions.en10.1109/ATEE66006.2025.11299960info:eu-repo/semantics/closedAccessCubesatSteerable AntennaRotation MechanismLow Earth Orbit (Leo) Satellite CommunicationWideband Antenna DesignSatellite Communication Technologies.Conference Object2-s2.0-105032343892WOS:001741236900093N/AN/A
