PURPOSE: Antenna assembly for improving antenna isolation is provided to improve a back lobe and a side lobe of a frequency by including a circuit board using a specific pattern and multiple layers. CONSTITUTION: An electric wave duplicator (20) copies a predetermined electric wave. The electric wave duplicator absorbs the predetermined electric wave. One or more reflectors (30) are formed with a side wall. The side wall is extended to an electric wave direction of the electric wave duplicator. A circuit board includes one or more layers. |
