Dual-polarized and multiple-layers micro-strip patch antenna for satellite mobile communication

According to the low profile request of satellite correspondence antenna, a kind of multi-stack micro-strip patch antenna is designed, and the dual ports are excited through H shaped aperture slots, respectively. A Parasitic patch is set on the top layer to improve the performance. Then each parameter of antenna is analyzed, and the VSWR is satisfied the requirement of satellite correspondence, and bandwidths of two ports can reach 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 much 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.
