چکیده:

This paper describes the design of a microstrip array for direct broadcast satellite reception. At first, a 4 × ۴ linear polarised subarray microstrip patch elements is designed. Then by changing the element spacing, the return loss and gain of the subaray is improved. Finally, using this improved subarray, a 16 × ۱۶ array is designed. The simulation results show that the array has a 250 MHZ bandwidth (VSWR<2). The significance of this work lies in increased gain of the subarray and hence achiving a 31 dBi gain with less elements than those reported in the litteratures, leading to less production costs.
