A Compact Flexible Crown Rectangular Fractal Antenna on low-cost PET substrate

Textile substrates and paper-based substrates are generally used to design the flexible antennas. However, these substrates have the issue of moisture absorbance which effect the antenna working. In the present work, a compact flexible crown rectangular fractal antenna has been fabricated and tested using copper tape (conducting material) and PET sheet (substrate). The proposed antenna is simulated and fabricated and the results are found in good agreement. Further, the results for prototype antenna are obtained in bent form. Also, the proposed antenna is compared with similar shaped antenna fabricated on RT-Duroid. The proposed PET substrate based antenna shows 53.17 % miniaturization capability with an advantage of flexibility compared to the earlier published antenna.
