Abstract
A low cost, flexible software antenna for ISM band is presented. The Novel antenna is proposed for ISM Band applications. Pure 100 % Cotton is used as dielectric substrate material with dielectric constant 1.6. This antenna is flexible and suitable for wearable applications. The designed antenna resonates at ISM (Industrial, Scientific, and medicine) band with a return loss of more than −25 dB. The simulated and measured results show the performance in terms of Return Loss, Radiation pattern which shows the efficiency of the proposed antenna and this flexible softwear antenna is measured in various bending environments are presented in this paper. Investigation focuses on an ordinary cotton cloth with 3 mm thickness, used as its substrate, and the patch and ground plane are made up of copper as conducting material together to form a flexible textile antenna. Proposed antenna is tested in various bending condition. Such Textile antenna designed for an ISM Band 2.45 GHz. Its radiation characteristics, return loss, gain, polarization have been examined which are the issues when it is used as a wearable antenna for medical purpose. Since it is a flexible textile antenna it bends for any condition. Observations were done for various diameter PVC pipes which is equivalent to the human body organs like arm, elbow, forearm, wrist or in the leg, ankle, knee, thigh and its resonant frequencies were noted. One of the advantages of these characteristics is once the antenna is flexible and bends in any condition then the specific absorption rate can be reduced, when this antenna is placed on the human body.
