| چکیده | ||
| In this paper novel reflect-array antenna elements are proposed using aperture-coupled dielectric resonator antenna structures. Using these new structures, wide phase range and wide frequency bandwidth (up to 28.5%) with parallel and linear phase curves are obtained. In each case, an array consisting of 289 elements was simulated using the finite integration technique (FIT). The arrays exhibit 3-dB gain bandwidth and radiation efficiency up to 28% and 56%, respectively. The results are validated using transmission line method (TLM). | ||
