Body-centric system which is generally used for monitoring and tracking is a technology involving RFID communication system. Currently, many researchers have investigated textile RFID tags integrated in the garments, however, few of them studies the wearable reader antenna. In this paper, a 1.8GHz textile dual-polarized antenna, which will be potentially used as a reader antenna, was designed and fabricated on the three-dimensional (3D) weaving machine with the basic materials of copper yarns and E-glass yarns. The two ports of the antenna achieved −10dB bandwidth of 33MHz (1810– 1833MHz) and 52MHz (1765–1817MHz) respectively and the highest isolation value was −19.9dB. The cross polarization levels were less than −20dB in the E- and H-planes of the two ports of the antenna. The antenna gains of port 1 and port 2 were measured to be 3.5dBi and 4.1dBi respectively. The performance data above shows the adequate and proper antenna properties of this designed textile antenna.
