Design issues of flexible antenna -A review

Abstract

Recent years has been observed increasing attention from both academic and scientific communities in the field of flexible technology. Flexible antennas have found their importance, when conventional antenna performance is very low because of its peripheral environment. This survey reviews the development of flexible antennas, their design, substrate material used and addresses various bending conditions tested on the antenna finds many applications in military, satellite, medical and defense fields. The antenna should get adjustable to any kind of surfaces. The careful study had been done using current researches going on in the field of flexible antenna technology. Such antennas have merits of compactness, light weight, low profile, cheap and easy to fabricate. Even though there are more survey papers on flexible antenna is available, they are restricted only to particular issues only. So, in this review, a comprehensive survey has been provided which deals with all the issues and challenges of flexible antenna. Thus this review will find out the perfect solution of designing and bending issues of flexible antenna. All the designs presented are of the recent development in flexible technology.
