This article presents the design and optimization of a deployable 1 m mesh reflector compatible with a 12U-class CubeSat. This antenna is designed for telecommunication and is compatible with NASA’s deep-space network (DSN) at ${X}$ -band (i.e., uplink: 7.145–7.19 GHz; downlink: 8.4–8.45 GHz) and Ka-band frequencies (i.e., uplink: 34.2–34.7 GHz; downlink: 31.8–32.3 GHz). Three right-handed circularly polarized (RHCP) antennas, both transmit and receive, are introduced here: ${X}$ -band only, Ka-band only, and ${X}$ -/Ka-band. For the ${X}$ -band-only antenna, a gain of 36.1 and 36.8 dBic is achieved at uplink and downlink frequency bands, respectively. This translates into an aperture efficiency of 72% and 62%. For the Ka-band-only antenna, a gain of 48.4 and 48.7 dBic is obtained at downlink and uplink frequency bands, which translate into an aperture efficiency of 62% and 72%, respectively.

用于 X 和 Ka 波段深空网络电信的一米可部署网状反射器

本文介绍了与 12U 级立方体卫星兼容的可部署 1 m 网状反射器的设计和优化。该天线专为电信设计，与美国宇航局的深空网络 (DSN) 兼容 ${X}$ -band（即上行链路：7.145–7.19 GHz；下行链路：8.4–8.45 GHz）和 K a- 频带频率（即上行链路：34.2–34.7 GHz；下行链路：31.8–32.3 GHz）。这里介绍三个右旋圆极化 (RHCP) 天线，包括发射和接收： ${X}$ - 仅带， K a- 仅限频段，以及 ${X}$ -/K a-乐队。为了 ${X}$ -band-only 天线，分别在上行和下行频段实现了 36.1 和 36.8 dBic 的增益。这转化为 72% 和 62% 的孔径效率。为了K a-band-only 天线，在下行链路和上行链路频段获得 48.4 和 48.7 dBic 的增益，分别转化为 62% 和 72% 的孔径效率。
