摘要
本研究旨在为小型卫星通信应用设计一种 Ku 波段跟踪、指令和测距（TCR）天线。所提出的设计结合了锥形对数螺旋天线（CLSA）和碟形天线，是一种适合安装在下一代小型通信卫星上的全向天线。这种 TCR 天线的新颖之处在于选择参数来增强其结构。因此，对辐射元件和馈电系统进行了优化，以减小天线的尺寸。因此，拟议的天线在 Ku 波段的上行链路频率上增益超过 6 dBi，在下行链路范围内增益高达 7 dBi，满足了系统实现任务目标的要求。
Ku-band tracking, command and ranging antenna design for small satellites communications applications
The objective of this study is to design a Ku-band tracking, command, and ranging (TCR) antenna for small satellite communications applications. The proposed design combines the conical log spiral antenna (CLSA) with the discone antenna, which is an omnidirectional antenna suitable for installation in next-generation small communication satellites. The novelty of this TCR antenna lies in the selection of parameters to enhance its structure. Consequently, the radiating element and feeding system are optimized to reduce the antenna's size. As a result, the proposed antenna achieves a gain exceeding 6 dBi for uplink frequencies in the Ku-band and it reaches up to 7 dBi for the downlink range which is responsive to the system requirement's to achieve mission objectives.
