In our proposed model, we assume that we will communicate with a high throughput satellite named ETS-9, which is scheduled to be launched in Japan. Therefore, we will first design a five hundred twelve-element array antenna that satisfies the requirements of ETS-9. As shown in Figure 5, the beam angle is adjusted by scanning the sub-array divided into sixty-four elements each. From the latitude and longitude of ETS-9 and Japan, we can calculate the elevation angle and azimuth angle of the ground AESA antenna to be forty-eight point seven degrees and one hundred seventy-one point four degrees, respectively.
