Abstract
This paper presents a dual-band optical imaging system-integrated patch antenna based on an anisotropic fractal for Earth-observation CubeSats. The antenna operates at S-band frequencies. The size of the antenna is chosen to match the end face of the CubeSats. The antenna's main characteristics are studied using simulation in Computer Simulation Technology (CST) software; prototypes are developed to verify these characteristics. Double-sided Glass Epoxy Sheet FR-4 is used to develop the antenna prototype. By studying the antenna prototype, realized gain up to 4 dBi and 2.15 dBi at two resonant frequencies of the antennas with different substrate heights are obtained. Small size, low cost, dual-band, and integration with the imaging system allow achieving the entire CubeSat system's efficiency.
