Abstract This article proposes a design technique to increase the sensitivity of Bluetooth headset antennas. A planar inverted F antenna was designed on the top printed circuit board (PCB) of a two‐board PCB. Digital noise was designed as a loop‐type source on the bottom PCB, representing general noise derived from digital circuits and digital noise generated from the main cable line. The proposed antenna design was analyzed by means of simulation and verified by means of measurements of a fabricated antenna. The proposed technique increased the measured sensitivity by 2.23 dB.
