[0002] Phased array antenna refers to an antenna that changes the shape of the radiation pattern by controlling the feeding phase of the radiating element 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. The key components of the phased array antenna are the phase shifter and the antenna radiating element. Phase shifters are divided into two types: continuous phase shifters and digital phase shifters. The phase shift value of the continuous phase shifter can change continuously within the range of 0° to 360°, and the phase shift value of the digital phase shifter is discrete. The phase shifter should ensure that the required phase shift value is obtained within a certain frequency range, and it is also necessary to meet certain requirements such as power resistance and temperature stability to ensure that the phased array antenna can work normally at different frequencies and under changing environmental conditions.
