ANTENNA SYSTEM FOR VARYING WIDTH, GAIN, AND TILT OF ANTENNA RADIATION PATTERN AND CONTROLLING METHOD THEREOF

摘要

PURPOSE: An antenna system for varying a width, a gain, and a tilt of an antenna radiation pattern and a controlling method thereof are provided to control the beam width of the antenna radiation pattern and the gain of the vertical beam by changing an overlapped area between an antenna feeding line and a dielectric. CONSTITUTION: An antenna system for varying a width, a gain, and a tilt of an antenna radiation pattern includes a plurality of antenna elements, a plurality of antenna feeding lines connected to the antenna elements, a plurality of dielectrics overlapped on the antenna feeding lines, and a tilt change unit for changing an overlapped area between the antenna elements and the antenna feeding lines. The tilt variation unit controls a vertical beam tilt of the radiation pattern. The antenna system further includes a fixing reflection plate(34) for fixing the antenna elements, a plurality of movable reflection plates(35a,35b) connected to both sides of the fixing reflection plate(34), and a beam width change unit for changing a tilt between the fixing reflection plate(34) and the movable reflection plate(35a,35b).
