摘要：天线收发模块是每颗卫星通信系统的必要部件。传统的卫星设计中，该模块由卫星内部收发电路、天线网络盒、收发天线以及必要连接电缆组成。在这种设计下，天线收发模块体积大，组成复杂，不利于cubesat卫星的设计、安装以及标准化模块组装。本课题提出一种cubesat卫星天线收发模块的新方案，在符合cubesat标准的单块电路板上，利用芯片化的天线，完成射频信号的收发、滤波、信号相位幅度调整、天线辐射等所有功能。该方案具有体积小、重量轻、方便模块化设计安装的诸多优点。

本文首先介绍了小卫星上通讯模块应答机的发展现状，以及发射机接收机前端几种基本结构；根据课题需要达成的任务指标，采用芯片天线FR05_S1_N_0_001作为天线收发模块中的天线，详细介绍了芯片选型以及收发机电路设计，并对电路性能做了详细分析，得到的分析结果满足设计指标；最后详细介绍收发电路PCB制版流程，利用Candece Allegro SPB 16.5进行PCB制版，并结合射频电路PCB制版要求详细分析了课题中电路板设计的具体注意事项，完成了微型天线收发模块的设计与制作。

Title Design of Cubesat Satellite Micro Antenna Receiving and Transmitting Module                                  

Abstract:Antenna transceiver module is a necessary component of each satellite communication system. In traditional satellite design, the module consists of satellite internal transceiver circuit, antenna network box, transceiver antenna and other necessary connection cable. In such design, the antenna transceiver module is not conducive to cubesat satellite design, installation and standardization of modular assembly with the disadvantages of bulky, complex structure. In this paper, a new scheme of cubesat satellite antenna transceiver module is proposed. All the functions of RF signal transmission and reception, filtering, signal phase amplitude adjustment, antenna radiation and so on are realized on a single block circuit board conforming to cubesat standard. The program has a small size, light weight, easy to modular design and installation of many advantages.

In this paper, the development status of the answering machine on the small satellite is introduced, and the basic structure of the transmitter receiver front end is introduced. According to the task index, the chip antenna FR05_S1_N_0_001 is used as the antenna in the antenna transceiver module. Selection and transceiver circuit design, and the circuit performance to do a detailed analysis, the results obtained to meet the design specifications; Finally detailed transceiver circuit PCB plate process, the use of Cadence Allegro SPB 16.5 PCB plate, combined with RF circuit PCB plate requirements Detailed analysis of the problem in the circuit board design specific considerations, completed the micro-antenna transceiver module design and production.
