Paragraph starter

The selection of polymer substrates is critical for the successful implementation of flexible antennas and chipless RFID tags in IoT applications. Research by Khan (2021) highlights that materials such as PET, PTFE, and PVC offer a compelling combination of flexibility, durability, and cost-effectiveness, though their electrical performance, particularly antenna radiation efficiency, can be significantly influenced by mechanical bending. This underscores the necessity for designers to rigorously test component performance under anticipated operational stresses.
