Design and Analysis of a 16 × 16 Microstrip Antenna for Direct Broadcast Satellite Reception

This paper describes the design of a microstrip array for direct broadcast satellite reception At first, a 4× 4 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× 16 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
