Conversion of an ultra-wide-band (UWB) antenna to dual-band antenna for wireless body area network (WBAN) applications

This paper proposes a dual-band microstrip patch antenna to operate at both WLAN Bluetooth band (2.2 GHz to 2.83 GHz) and ultra-wide-band (4.7 GHz to 12.69 GHz). The proposed antenna is a modified version of an UWB microstrip antenna. The antenna's radiation pattern is almost quasi/partial omni-directional and its highest gain level is reached to 5.23 dB. This antenna can be used for wireless body area network (WBAN) sensors, which currently rely on Bluetooth and UWB frequency Besides, this antenna may found other possible areas of operation e.g. wireless router, RFID tag, GPS tracker, ambient RF energy harvesting at the frequency range of ISM bands.
