MIMO ANTENNA APPARATUS

摘要

PURPOSE: A MIMO(Multiple-Input Multiple-Output) antenna device is provided to prevent interference between antenna elements by isolating antenna elements through a band stop device. CONSTITUTION: A first and a second antenna elements(130,140) resonates in a fixed frequency band. A band stop device(150) is arranged between the first and the second antenna element. The band stop device isolates the first and the second antenna element. The band stop device comprises a blocking series inductor, a blocking series capacitor, and a blocking parallel capacitor. The blocking series inductor is serially connected to the first and the second antenna element. The blocking series capacitor is connected to the blocking series inductor in parallel. The blocking parallel capacitor is connected to the first and the second antenna element, the blocking series inductor, and the blocking series capacitor in parallel.
