Antenna device configured for mixed beam scanning

An antenna device for mixed beam scanning, comprising:

• a multiple-sided carrier frame having a plurality of structural planes, each positioned with respect to a central axis in a configuration that the plurality of structural planes are distributed around the central axis;
• a plurality of antenna modules, each configured to be mounted on and exposed from a corresponding one of the plurality of structural planes and perform electronic scanning in a one-dimensional direction;
• a plurality of active radio-frequency (RF) modules, each electrically connected to the plurality of antenna modules and configured to generate an active RF signal and transmit the active RF signal to a corresponding one of the plurality of antenna modules, so that the antenna module forms a radiation beam based on the active RF signal, wherein each of the plurality of antenna modules is configured to receive at least one external RF signal and transmit the at least one external RF signal to a corresponding one of the plurality of active RF modules;
• a pivoting portion having a first end disposed at a lateral side of the multiple-sided carrier frame and extending along a first extending direction, wherein the multiple-sided carrier frame is configured to spin around an axis defined by the first end of the pivoting portion;
• and
• a rotating portion having an end directly or indirectly connected to a second end of the pivoting portion, extending along a second extending direction substantially perpendicular to the first extending direction, and configured to drive the multiple-sided carrier frame to spin or revolve around an axis of the rotating portion to compensate or enhance a scanning capacity of the plurality of antenna modules in another dimension, and drive the plurality of antenna modules to rotate as a whole along a rotating direction different from a spinning direction of the multiple-sided carrier frame.
