Military field deployable antenna using origami

Abstract

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.
