Abstract

An adaptive deployable patch antenna with a shape recovery function is proposed in this research. In the previous paper, it was shown that materials with high tangent dielectric, which were considered unsuitable for antennas, can be used in antenna substrates that have undergone significant mass reduction using topology optimization. Therefore, in this research, we adopted a shape memory polymer, which is a polyurethane material that is also known unsuitable as an antenna substrate material, and showed its utility value as an adaptive deployable patch antenna with a shape recovery function. In addition, we investigate how the antenna characteristics are affected by the mass reduction rate of the substrate, and report the changes in the resonance frequency, antenna gain, and antenna pattern.
