An integrated two-wire helical antenna for Bluetooth application

An integrated two-wire helical antenna for Bluetooth band (2.4 ~ 2.483 GHz) is introduced. The proposed antenna is implemented on the printed circuit board (PCB) for Bluetooth. The antenna has modified two-wire helical structure to maximize the bandwidth in spite of small PCB volume. The dimension o...

More Information
Summary:An integrated two-wire helical antenna for Bluetooth band (2.4 ~ 2.483 GHz) is introduced. The proposed antenna is implemented on the printed circuit board (PCB) for Bluetooth. The antenna has modified two-wire helical structure to maximize the bandwidth in spite of small PCB volume. The dimension of proposed antenna on standard FR4 substrate is 12 mm times 4 mm times 1.6 mm. The impedance bandwidth (VSWR<2) of proposed antenna is about 150 MHz (2.39 ~ 2.54 GHz). Radiation patterns are nearly omni-directional for operation frequencies.
