摘要

本文提出了一种用于军事野战部署的折纸天线。介绍了一种高增益四面体折纸天线(天线#1)，然后扩展到圆极化天线(天线#2)，用于军事卫星应用。两种天线均采用折纸四面体结构在纸基板上实现。天线1的辐射孔径包括一个三角形单极子和两个条形导向器。制作的天线#1在2.6 GHz时的峰值增益为9.6dBi，阻抗带宽为66% (2-4 GHz)。天线2的圆极化特性是通过激励两个相同的三角形单极元来实现的。两个元件都由相位差为90°的t结分压器馈电。所提出的天线#2的3db轴比带宽和阻抗带宽分别为8%(3.415至3.7 GHz)和70.2%(2.4至5 GHz)。

Military field deployable antenna using origami

In this paper, origami antennas are proposed for military field deployment. A high gain tetrahedron origami antenna (antenna #1) is introduced and then extended to circularly polarized antenna (antenna #2) for military satellite applications. Both the antennas are realized on paper substrate by using origami tetrahedron structure. The radiating aperture of antenna #1 comprises a triangular shaped monopole and two strip directors. The fabricated antenna #1 demonstrates a peak gain of 9.6dBi at 2.6 GHz with impedance bandwidth of 66% (2–4 GHz). The circular polarization characteristics of antenna #2 is achieved by exciting two identical triangular shaped monopole elements. Both the elements are fed by a T-junction divider with a phase difference of 90°. The 3-dB axial-ratio bandwidth and impedance bandwidth of the proposed antenna #2 are found to be 8% (3.415 to 3.7 GHz), and 70.2% (2.4 to 5 GHz), respectively.
