ABSTRACT:
An antenna assembly has an antenna set, a rotation assembly and a control circuit for driving the rotation assembly to rotate to adjust receiving angel of the antenna set. The control circuit can learn to adjust remote signals represented different channel number on a remote control to automatically control the receiving angle and direction of an antenna set. Thus, the antenna assembly can be suitable to general remote control to automatically adjust the antenna set to search the wireless bands. Besides, the control circuit further stores data related to the wireless bands with the corresponding channel number to be easy for user turn to specific wireless band without searching step.
