The Transparent Monopole Antenna for WCDMA and WLAN

The transparent monopole antenna is proposed for wireless local area network (WLAN) in 5.2 GHz and wide-band code-division multiple-access (WCDMA) applications. In general, most of antennas in use now are fabricated on FR-4 PCB board or other microwave substrates. But in this design, the proposed antenna is fabricated on a thin polyethylene terephthalate (PET) plastic coated by indium tin oxide (ITO), and has following characteristics: flexible, transparent, small, light volume, and wide bandwidth of 0.42GHz at 1.97 GHz, 1.19 GHz at 5.58GHz.
