Abstract

CubeSats are now becoming increasingly popular for space programs. This is because of their affordability. Moreover, CubeSats can be built using commercial Off-the Shelf (COTS) components. They are cost effective compared with traditional satellites. CubeSats can communicate with each other within a swarm, and with ground station. These capabilities require CubeSats to be equipped with small antennas to facilitate cross-link or downlink communications. Therefore, in this paper, we present a novel design of high gain printed Yagi-Uda antenna and a two element Yagi-Uda antenna array which can be perfectly attached on 3U CubeSat's aluminum bodies to avoid deployment. We have shown a numerical analysis of Yagi antenna array and simulated the antenna using the High Frequency Simulator Structure (HFSS). The simulation model is completed with the existing of CubeSat mental body. Our results show that the antenna array achieves good impedance matching with a return loss of − 26.47 dB at the desired frequency of 2.47 GHz, a −10dB impedance bandwidth of 134 MHz (2.396–2.530 GHz) and has a total gain of 6.41dB.

立方体卫星上打印的八木uda天线阵列

立方体卫星在太空项目中越来越受欢迎。这是因为他们负担得起。此外，立方体卫星可以使用商用现货(COTS)组件构建。与传统卫星相比，它们具有成本效益。立方体卫星可以在群内相互通信，也可以与地面站通信。这些能力要求立方体卫星配备小型天线，以促进交叉链路或下行通信。因此，本文提出了一种新型的高增益印刷Yagi-Uda天线和一种双单元Yagi-Uda天线阵列，该天线阵列可以完美地附着在3U CubeSat的铝机身上，从而避免部署。本文对八木天线阵列进行了数值分析，并利用高频模拟器结构(HFSS)对天线进行了仿真。仿真模型是在已有立方体卫星精神体的基础上完成的。结果表明，在期望频率为2.47 GHz时，天线阵列阻抗匹配良好，回波损耗为- 26.47 dB，阻抗带宽为134 MHz (2.396-2.530 GHz)，总增益为6.41dB。
