SoftWear antenna is an arrangement of Wearable and textile antenna properties which is flexible in two dimensions. Softwear antenna serves as element of clothes and it should not affect the wearer by means of any radiation persevere in it. It is deliberate in such a way to perform in close propinquity to human body antenna substrate made of fabrics. This paper gives evidences about those for the design and development of softwear textile antenna. Nowadays wireless technology has challenges to construct a device with compact size, lightweight, low profile and ease in its fabrication. A right choice for such type of antenna is a softwear microstrip patch antenna. This type of antenna uses textile substrate. In this paper various cotton substrates and polyester substrate have been compared with two feeding Techniques namely line feed, co-axial feed. The performance of the softwear antenna shows that polyester substrate gives good results when compared with cotton as a substrate in both feeding techniques Basic rectangular patch have been considered. The working frequency of this antenna is 2.45GHz.It is well-known to use in wireless body area network (WBAN).Wireless Body centric communication is also possible in this Type which uses the frequency of Industrial, Scientific, Medicine meant by ISM band(2.45 GHz).This softwear antenna using polyester substrate was fabricated and its S11 and VSWR was measured using network analyzer.
