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.

本文提出了一种基于各向异性分形的双波段光学成像系统集成贴片天线，用于地球观测立方体卫星。天线工作在 S 波段频率。选择天线的尺寸以匹配立方体卫星的端面。使用计算机模拟技术（CST）软件中的模拟来研究天线的主要特性；开发原型来验证这些特性。双面玻璃环氧树脂板FR-4用于开发天线原型。通过对天线原型的研究，在不同基板高度的天线的两个谐振频率下，实现了高达4 dBi和2.15 dBi的增益。体积小、成本低、双频段、与成像系统集成，可实现整个 CubeSat 系统的效率。
