Study on antenna beam tilting for flat SOTM on vehicle

This paper is based on the direction of low profile and miniaturization for SOTM on vehicle, the performance of beam tilting technique is studied and analyzed according to flat antenna structure, and the performance of insulating vehicle attitude changes is simulated based on angular position compensation, the results indicate that the flat SOTM applying beam tilting technique could reduce height effectively while adds some burden on hardware of azimuth, elevation and polarization compensation. The technique applied and results obtained are instructive for engineering.
