The embodiment of the invention relates to the technical field of antennas, and discloses an antenna circuit, a circuit board assembly and wireless Bluetooth equipment. The antenna circuit comprises an antenna unit, a touch detection chip, an analog-to-digital converter and a Bluetooth chip; the antenna unit is connected with the touch detection chip through the analog-to-digital converter; the analog-to-digital converter is used for converting the analog form signal sent by the touch detection chip into a digital form signal and sending the digital form signal through the antenna unit; and the antenna unit is further connected with a Bluetooth chip, and the Bluetooth chip sends or receives signals through the antenna unit. Compared with a mode of separating a touch circuit from a Bluetooth circuit in the prior art, a mode of integrating the antenna units in the embodiment is advantageous in that the hardware cost is saved, the blocking effect of the touch circuit on the signals received or sent by the antenn
