[0002] A phased array antenna refers to an antenna that changes the shape of its radiation pattern by controlling the feeding phase of the radiating elements in the array antenna. Controlling the phase can change the direction of the maximum value of the antenna radiation pattern to achieve the purpose of beam scanning. When in use, a phased array antenna requires a supporting mechanism to be installed outdoors.
