Abstract

The antenna of the satellite communication on-the-move (SOTM) system generally is reflector antenna. Reflector antenna can not be applied on moving vehicle widely because of restrictions on dimensions and aerodynamics. Low profile phased array antenna is a good solution to this problem. When low profile phased array antenna is applied, the reduced height of the planer antenna causes some problems such as the decrease of antenna performance. Genetic algorithm optimization is applied to adjust the subarray distances to reduce the sidelobe of the antenna beam pattern. Computer simulation results show that the sidelobe of the low profile phased array antenna is suppressed by 7.1 dB after optimization.
