In order,a multi-stack micro-strip patch antenna with dual ports excited by H shaped aperture slots is designed to meet the low profile requirement of satellite correspondence antenna.A Parasitic patch is set on the top layer to improve the performance.Then each parameter of antenna is analyzed,and the VSWR satisfies the requirement of satellite correspondence with bandwidths of two ports being 22% and 30.6% (VSWR<2) respectively.Isolation of two ports is higher than 30 dB,and the beam width of dual polarization of two ports are greater than 70 degrees.The simulation results show that the antenna can be applied in engineering projects,and can be a satellite communication terminal to realize receiving and transmitting function.

Key words: satellite communication;dual polarization;multi-stack;micro-strip patch antenna
