Calibration unit of base station antenna and base station antenna

The invention relates to a calibration unit of a base station antenna and the base station antenna. The calibration unit comprises a main body part, a radio frequency conductor and a receiving circuit board. The main body part is provided with a cavity, the radio frequency conductor is located in the cavity, and the receiving circuit board is installed on the main body part, located outside the cavity and used for receiving coupling signals of the radio frequency conductor. A preset distance is arranged between the radio frequency conductor and the receiving circuit board, and the radio frequency conductor is provided with a bending section which can protrude or sink towards the direction of the receiving circuit board. The receiving circuit board is arranged outside the cavity, so that the calibration unit can be matched with different receiving circuit boards, and the application field of the calibration unit is expanded. The isolation degree between the radio frequency conductor and the receiving circuit b
