| Abstract |
In a phased array antenna, the beam steering angle error is occurred by a quantization of a phase shifter. For analysis of the beam steering angle error, the simplified equations were induced and presented in the case of linear and plane phased array antenna. The presented equations were verified by comparing it with simulation based on array factor with quantized phase shifting values. Using the verified equations, we presented the indices related to beam steering angle error, resolution of phase shifter and configuration of array for design of phased array antenna. |
