Design & Fabrication of Carbon Nano-structured Flexible Antenna

With a development and an increasing interest in flexible electronics, for civil, medical, space, and military domains, we present a design of a patch antenna using CNT-polymer ink on fabrics. We have prepared CNT ink, and measured its properties to use as a conducting material for making patches. The antenna is designed on cotton and Songket fabric that resonates at 2.3GHz on a 1.23 mm, and 1.06 mm thick fabric substrate with epsilon(T) approximate to 1.7, and epsilon(T) approximate to 1.9 for cotton and Songket respectively. Measured and simulation results shows that band width depends on thickness and type of fabrics we used. All antenna parameters such as VSWR, return loss, gain and radiation pattern meet the design criteria.
