Abstract： A spaceborne phased array antenna with high-gain, circular polarization and wide-angle is designed to meet the requirements of large range data transmission of X-band communication system. The antenna array element is fed by the bottom feed, the circular-polarization is realized by the angle cutting technology and the miniaturization is realized by the slot technology. The array is arranged in staggered layers, so that the radiation performance is the best. Through reasonable layout and optimization design of transmitting module, beam control module and power module, the beam can be changed within 0～60° off-axis angle and 0～360° azimuth angle. The test results of this machine are good after machining, which has a certain guiding significance for the design of X band communication system, especially the phased array antenna.
