Abstract
The ILS electromagnetic environment can easily be changed by large objects reflection, which result in degradation of the signal-in-space. Therefore, how to choose a suitable localizer antenna is very important. The higher the operating category of ILS is, the stricter requirements for the localizer course structure will be, especially for Category Ⅱ/III, In the paper, three typical antennas are compared by computer simulation, and the results show the scalloping of course structures under different types of antennas. Computer simulation is very helpful to study the selection of localizer antenna for ILS Category Ⅱ/III. Computer simulation can identify the structure disturbance before construction and help engineers find solutions. This can also effectively protect electromagnetic environment of the airport and ensure operation safety.
