最近，关于微型卫星的研究取得了很大的进展，特别是那些将微型卫星视为更大星座或群的一部分的研究。这一特点使微型卫星能够提供高时间分辨率的观测数据和冗余。特别是，它减少了对卫星对地面通信的需求，因此有助于节省能源，并允许在卫星本身上执行分布式处理算法。因此，卫星对卫星或交叉链路通信至关重要。为了实现这些优势，用于微型卫星的交联天线必须满足许多标准，即体积小、重量轻、低功耗、高增益、宽带宽、圆极化和波束可操控性。迄今为止，还没有研究现有平面天线设计是否适合用于微型卫星。为此，本文通过关注能够实现高增益、波束导向和宽带宽的微带贴片和缝隙天线，为文献做出贡献。本文综述了66种平面天线设计，包括38个贴片和28个槽的天线。此外，我们从质量、尺寸、增益、波束可操控性、极化类型、工作频带和回波损耗等方面对这些天线进行了广泛的定性比较。此外，我们还评估了三种天线设计，这些设计最好地解决了通用平台上的微型卫星挑战。我们发现不对称的e型贴片天线设计最适合在2U立方体卫星上使用。这是因为它的体积小（34 × 13 mm2）和高增益（7.3 dB）。此外，e型贴片天线具有2300mhz的- 10db宽带宽和-15.2 dB的小回波损耗。
Works on pico-satellites have gained momentum recently, especially those that consider pico-satellites as part of a much larger constellation or swarm. This feature allows pico-satellites to provide high temporal resolution of observational data and redundancy. In particular, it reduces the need for satellite-to-ground communications and, hence, helps save energy and allows the execution of distributed processing algorithms on the satellites themselves. Consequently, satellite-to-satellite or cross-link communication is critical. To realize these advantages, the cross-link antenna employed on pico-satellites must meet many criteria, namely, small size, lightweight, low-power consumption, high gain, wide bandwidth, circular polarization, and beam steerability. To date, no works have examined the suitability of existing planar antenna designs for the use on pico-satellites. To this end, this paper contributes to the literature by focusing on microstrip patch and slot antennas that have the ability to achieve high gain, beam steering, and wide bandwidth. This paper reviews 66 planar antenna designs, which includes 38-patch and 28-slot antennas. In addition, we provide an extensive qualitative comparison of these antennas in terms of their mass, size, gain, beam steerability, type of polarization, operating frequency band, and return loss. In addition, we have evaluated three antenna designs that best address the pico-satellite challenges on a common platform. We find that the asymmetric E-shaped patch antenna design is the most suitable for the use on 2U CubeSats. This is because of its small size (34 × 13 mm2) and high gain (7.3 dB). In addition, the E-shaped patch antenna yields a wide -10-dB bandwidth of 2300 MHz and a small return loss of -15.2 dB.
