Generally, a phase array antenna calculates an array component using a phase delay of a signal. The phase array calculation method using the phase delay has the advantage of easy calculation; however, it is unsuitable for calculating the phase array performance in a wide frequency band, primarily because the electric length calculated at a single frequency. In this paper, an array antenna calculation method using the time delay is introduced. The proposed method has the advantage of being able to calculate the performance without being affected by the frequency as it is calculated using the speed of radio waves. Moreover, it can calculate errors that are difficult to understand in the calculation that uses the phase delay. The two calculation methods are compared using MATLAB. As a result of the calculation, it is possible to simultaneously calculate the frequency band of 30 to 50 GHz for 5 dipoles in a uniform linear array environment, and the error rate was less than 0.2 %. Accordingly, efficient calculation of wideband arrayed antennas can be achieved by applying the arrayed antenna signal processing method using time delay. Furthermore, it is expected to be applicable in the field of phased array performance analysis simulator.
