Abstract

The CubeSat concept has become very popular with both university groups and researchers, space agencies, governments and companies. CubeSat offers a fast and affordable way for a wide range of stakeholders to be active in space. Due to the high degree of modularity and widespread use of off­the­shelf commercial subsystems, CubeSat projects can be prepared for flight much faster than using traditional satellite schedules usually within one to two years. In this paper, we have considered a model of an S and X band patch antenna for CubeSat nanosatellites in the field of Earth remote sensing (ERS). The antenna dimensions were determined and designed according to the dimensions of the small spacecraft. The shape of the emitting part was formed using a geometric fractal with an anisotropic structure. Using the CST Microwave Studio software package, the electro­dynamic, frequency characteristics and directional properties of the antenna were determined. The results of computer simulations demonstrate that the developed antenna concept has a multi­band property and meets all the parameters that are necessary for receiving and transmitting data in the S and X bands. It was also found that the anisotropic fractal structure allows the antenna to have several operating frequencies.

立方体卫星纳米卫星的S和X波段贴片天线
立方体卫星的概念在大学团体和研究人员、航天机构、政府和公司中都很受欢迎。CubeSat为广泛的利益相关者提供了一种快速、实惠的太空活动方式。由于高度模块化和现成商业子系统的广泛使用,CubeSat项目的飞行准备速度比使用传统卫星时间表快得多,通常在一到两年内。在本文中,我们考虑了地球遥感领域中立方体卫星纳米卫星的S和X波段贴片天线模型。天线尺寸是根据小型航天器的尺寸确定和设计的。发射部分的形状是使用具有各向异性结构的几何分形形成的。使用CST Microwave Studio软件包,确定了天线的电动态、频率特性和方向特性。计算机仿真结果表明,所开发的天线概念具有多波段特性,满足在S和X波段接收和传输数据所需的所有参数。还发现各向异性分形结构允许天线具有几个工作频率。
