There is provided an antenna device having a learning function and capable of searching and memorizing wireless frequency bands. A control circuit is used to automatically control the receiving angle and direction of an antenna set. When the strongest frequency band is found by the antenna set, a remote control is used to control the circuit for recording the current angle and direction into a memory unit. Afterwards, a user can directly select a pre-stored band identification number to conveniently adjust the antenna device to have the best receiving angle and direction the corresponding capable of receiving the band, thereby decreasing the time to adjust the antenna.
