High Bandwidth Perovskite based Antenna for High-Resolution Biomedical Imaging at Terahertz

This paper suggests the prospective utilization of a hybrid perovskite, with a chemical name of Methylammonium Lead Iodide (CH₃NH₃PbI₃), in the design of a Terahertz (THz) antenna. A newly developed perovskite material has been used for the antenna design which can replace the conventional metallic patches. The proposed antenna operates in two THz bands, i.e. 3.6-7.4 THz and 8.25-10.0 THz. The realized gain of the antenna is above 4 dBi and efficiency is above 70% in overall operating bandwidth. The reported performance of the antenna design provides the proof of the concept for the possible utilization of non-metallic advanced materials such as perovskite in manufacturing antennas for THz based biomedical applications.
