Design of RFID Textile Dipole Antenna

A textile dipole antenna is presented. Based on the theory of dipole antenna, according to the selection of fabric weaving materials, the paper get an optimal material and structure textile antenna design according to the thickness of conductive fibers, fabric weaving density and the comparative analysis of the electromagnetic properties of the braided structure. The proposed antenna consists of two parts: one part is the polyester, the other two parts are metal wires. The copper fiber with a diameter of 0.1mm is applied to the design of the textile antenna. The density of copper fiber is 250 × 250 in100 square centimeters. The proposed textile antenna can cover 915MHz with 75MHz bandwidth.
