Abstract

Antennas used in the Aerospace and Defense industry are often installed on structures that are electrically large with respect to the wavelength, such as ships, trucks, tanks, aircraft, etc.
Since in most cases measurements are impractical, electromagnetic simulations are necessary for estimating the impact of such structures on the radiation pattern of antennas with respect to the free-space scenario.
CST's hybrid solver has proven to be suitable for carrying out these analyses of pattern deformation, especially when the antenna and platform domains require different solvers.
Here, we present a case study in which the different antennas are integrated onto a pan/tilt platform, which in turn is installed on the side of a ship. The simulation setup and some strategies for simplifying the simulations are presented.
Finally, some effects of the installation conditions and their impact on RF system performance are discussed.
