The present invention provides a multiband antenna and a switching control mechanism for phase modulation thereof. The mechanism comprises an output gear, a linear running mechanism, and a circumferential rotating mechanism; the linear running mechanism is used for controlling the output gear to be switched among a plurality of positions in the axial direction of the output gear, so that the output gear is connected to any one of a plurality of frequency selection and phase modulation units at two of the plurality of positions; the circumferential rotating mechanism is used for controlling the output gear to rotate circumferentially; for each frequency selection and phase modulation unit, at a first position, the output gear is linked with a transmission nut in the frequency selection and phase modulation unit to run linearly and suitable for using an outer gear thereof to align with any one of a plurality of phase modulation control members; and at a second position, the output gear is linked with the transm
