An antenna diversity system using an active antenna is disclosed. The disclosed system may include: a first antenna configured to transmit and receive a signal of a first frequency band; a second antenna configured to transmit and receive a signal of a second frequency band; and an active circuit unit implemented by active elements. In a first mode, the second antenna is operated as a passive antenna, and in a second mode, the second antenna is electrically connected to the active circuit unit and operated as an active antenna. The disclosed diversity system has the advantages of using a diversity antenna without increasing the size of a terminal, and of using an active antenna as a diversity antenna. |
