종이접기와 키리가미 이론에 기반한 3차원 T-자형 다이폴 안테나 설계

Abstract

In this study, the design of a 3D foldable T-shaped dipole antenna inspired by origami and kirigami theory is presented. The origami- and kirigami-inspired techniques map 2D to 3D space. Moreover, the lamina emergent torsional (LET) joint is designed to fold the planar structure. The proposed antenna, including the LET joint, is printed on a planar 0.5 mm thick FR4 substrate. The proposed antenna is fed by a capacitively coupled microstrip line to achieve a 20 % fractional bandwidth (2.7~3.3 GHz), with a measured antenna gain value of 6.5 dBi.
