In our analysis in this paper we have improved the design of microstrip antenna array to be used in the non-geostationary satellite systems with electronically steerable beam which can trace the desired earth station on Earth without any need to change the angle of the cube satellite in space so we can save the batteries on the satellite board with low cost, easy to fabricate antenna, The array antenna consists of multiple patches and multi feeders with different phases to control the steerable beam electronically, The antenna array operates in Ka frequency bandwidth and consists of 6*6 elements with gain reaches 18.8dBi, each element in the array has the dimensions of ( 4.6mm * 2.6mm ) with rounded edges and the total size of the antenna array is (5.43 cm * 3.33 cm), there are narrow strip fences applied between elements to reduce the effect of mutual coupling and in accordance reduce the sidelobe level of the antenna array.
