Contents I. Introduction
Terahertz (THz) communication systems offer superior performance with their rapid data transfer rates, robust resistance to interference, and dependable reliability, setting them apart from conventional microwave communication technologies [1]. Due to the demands of modern communication for characteristics such as high capacity, ultra-wideband, and high reliability [2], this inevitably leads to an increase in the number of subsystems, as well as complex electromagnetic compatibility issues, which constrain the performance of the entire communication system. However, reconfigurable antennas offer higher flexibility and adaptability, enabling them to switch between working frequency bands freely according to different application requirements, thus achieving different functions. Therefore, reconfigurable antennas provide a new direction for addressing these issues and have garnered widespread attention from researchers [3–5].
