Abstract

A novel design of a high-frequency multiband with a circular polarisation antenna based on a four-patch antenna system consolidated with an Archimedean spiral antenna for CubeSat applications. The geometry and size are compatible with the CubeSat standard structure dimensions of 10 × 10 cm². The antenna consists of a spiral antenna in the middle of four patch antennas surrounding it; the first antenna structure consists of two sets of two orthogonal identical patch antennas with a 90° phase shift to cover the band from 1.55 to 1.94 GHz at L-band, 2, 2.1, and 2.3 GHz at S-band, the second antenna is an Archimedean spiral antenna to cover all C-bands, all X-bands, all Ku-bands, all K-bands, and from 26 to 29 GHz at Ka-band. The measured results show that the reflection coefficients (S₁₁) and (S₂₂) achieve < −10 dB and the axial ratio achieves <3 dB, with a reference impedance of 50 Ω. The simulated and the measured results give a better agreement.

可在 S、C、X、Ku、K 和 Ka 波段工作的多波段圆极化立方体卫星天线

一种新颖的高频多波段圆极化天线设计，它基于一个四补丁天线系统，并与一个用于立方体卫星应用的阿基米德螺旋天线相结合。其几何形状和尺寸与立方体卫星的标准结构尺寸（10 × 10 cm2）相匹配。该天线由一个螺旋天线和围绕它的四个贴片天线组成；第一个天线结构由两组相移 90° 的正交相同贴片天线组成，覆盖 L 波段 1.55 至 1.94 GHz、S 波段 2、2.1 和 2.3 GHz 的频段；第二个天线是阿基米德螺旋天线，覆盖所有 C 波段、所有 X 波段、所有 Ku 波段、所有 K 波段以及 Ka 波段 26 至 29 GHz 的频段。测量结果显示，参考阻抗为 50 Ω 时，反射系数 (S11) 和 (S22) 达到 < -10 dB，轴向比达到 < 3 dB。
