Abstract

Frequency reconfigurable antennas play a prominent role in telecommunication technologies. This paper presents a reconfigurable antenna that could define the stretch properties in association with the intrinsic strain sensing capabilities. The stretchable resin is synthesized using Magnesium Nitrate Hexahydrate, Aluminium Nitrate Nanohydrate, the mixture was reduced and polymerized and finally made conductive stretchable resin with the help of CNT’s (Carbon Nano Tubes). The solution is characterized by the help of SEM and EDAX measurements. The conducting stretchable polymer resin could elongate upto 100% along with the fabric dielectric, Lycra. The electrical conductivity of the resin is 8 S/m. The precise dimension of the antenna was done with the help of a micro-cutter. The inverted S shape of the antenna helps to achieve bandwidth. The fabricated antenna operates within 4GHz and 8GHz with a gain of up to 3.3dB, Front to the Back ratio of 7.42. It is experimented by varying the strain to achieve frequency reconfiguration ranging from 0% to 75%. The fabrication and characterization of extremely efficient stretchable and reconfigurable antenna for C band frequency applications are described. As a potential application, the work can be demonstrated with the use of a highly stretchable and deformable antenna for deployable soft robotic applications..
