摘要

卫星通信在5G及以后5G生态系统中的重要性已得到广泛认可。低轨道和卫星的不断运动要求地面终端的自适应天线阵列。本文针对广泛应用于卫星通信的k波段设计了一种单贴片元件。该天线具有宽带宽和高可切换极化性能(在2.2 GHz范围内轴比< 3 dB)。所有结果都表明，这种结构非常适合在从太空广播时使用的大型数组中实现。

Compact Circularly Polarized Aperture Fed Patch Antenna for LEO Satellite Constelations

The importance of satellite communications in the 5G and beyond 5G ecosystem has been widely recognized. Low orbits and the constant movement of satellites demand for adaptive antenna arrays in ground terminals. In this paper, a single patch element is designed for the K-band, broadly used in satellite communications. The antenna exhibits wide bandwidth and high switchable polarization performance (axial ratio < 3 dB over 2.2 GHz). All results sustain that this structure is a great candidate to implement in larger arrays used when broadcasting from space.
