Abstract
In this paper, a rectangular fractal patch antenna for satellite communication is presented. The antenna is designed at frequency 20GHz. The antenna structure is depicted and inspected using 3-D finite difference time domain (FDTD) method and the results are compared with obtained by commercial software Ansys HFSS and experimental results. It is found that FDTD simulation results along with fabricated and HFSS simulations are agreed adequately. The return loss of the antenna operating is -33.14 dB and gain is 17dB. These results infer that the proposed antenna is well suitable for Satellite communication at Ku band and has large bandwidth.
