摘要

本文提出了一种用于立方体卫星的高增益圆极化法布里-帕姆罗天线。其中一个关键思想是采用5 × 5的Metasurface实现空腔，以提高所提出的天线设计的总增益。辐射贴片元件的两个相对角被截断以实现右圆偏振(RHCP)。仿真结果表明，该天线具有高达9.4 dBi的高增益，- 10 dB带宽为12% (2.42 ~ 2.73 GHz)， 2.5GHz时反射系数为- 15.6 dB, 2.5GHz时轴比为- 3dB带宽为1.6%。

High Gain Circularly Polarized Fabry-Pérot Antenna for S-band CubeSat Applications

This paper presents a high gain circular polarized Fabry-Pérot antenna for CubeSat applications. A key idea is the implementation of cavity using a $5\times 5$ Metasurface ground surface to improve the total gain of the proposed antenna design. The two opposite corners of the radiating patch elements are truncated to achieve a right-hand circular polarisation (RHCP). The presented simulation results show that the proposed antenna provides a high gain of 9.4 dBi, −10 dB bandwidth 12% (2.42-2.73 GHz) with a reflection coefficient of −15.6 dB at 2.5GHz and a −3dB axial ratio bandwidth of 1.6% at 2.5GHz.
