An antenna device with a swinging mechanism includes at least one antenna module, at least one active radio-frequency module, and at least one swinging portion. The antenna module can transmit at least one active radio-frequency signal outward and receive at least one external RF signal from the outside. The active radio-frequency module can be electrically connected to the antenna module and control the phase and amplitude of the active RF signal so that the antenna module can form a focused radiation beam of the active RF signal and control the generation of a radiation pattern by the antenna module for receiving the external RF signal. The swinging portion is connected to the antenna module and can swing the antenna module along a circular arc around a center of circle defined by a central support point to supplement an ability of the antenna module in scanning in a one-dimensional direction.
