다이폴 상태와 루프 상태로 변환 가능한 종이접기 방식의 종이 안테나

초록

A pattern-switchable origami antenna is designed with paper using inkjet-printing technology. The proposed antenna can be switched between loop and dipole antenna modes by folding and unfolding the paper, respectively. The proposed antenna is designed for the resonant frequencies of both modes to be 1.85 GHz. Eutectic gallium-indium liquid metal is introduced in order to avoid cracks in the conductive ink when the paper is folded. The performance of the proposed antenna is demonstrated through simulation and measurement results and antenna gain of dipole-mode and loop-mode are —4 dBi and —5 dBi, respectively. Also, the nulls of both dipole and loop modes compensate nulls from each mode.
