TY - THES A1 - Schmidt, Marius T1 - EM-Radome Design with MATLAB N2 - Radome-enclosed antennas are crucial elements of numerous aerial, maritime and ground applications. While they must be optically transparent to the transmitted and received radio frequency, radomes are often subject to various requirements from aerodynamics to loads requirements. Thus, designing a radome is a challenging task which is often solved by using computation-intensive numerical methods. To minimise this effort and to provide a user-friendly calculation tool, a MATLAB script has been developed to compute transmission and reflection coefficients of multilayered dielectrics. The verification and functionality of the MATLAB script was confirmed by various test cases with FEKO using the Method of Moments and FEM calculation. The research question based on this was then to carry out the numerical thickness optimisation of a monolithic and an A-sandwich wall design, and to determine the superior design style. The optimisation was applied to a frequency range in the X band and the Ka band with incidence angles ranging from 0◦ to 45◦. In the X band, the A-sandwich performed by 1.422 % better than the monolithic radome regarding the angle averaged transmittance at the operational centre frequency. At 23.8 % of the monolithic radome’s area density, considerable weight savings are to be expected. However in the Ka band, the angle dependence of the sandwich radome surged for the selected material setup and made the monolithic design with constant wall thickness perform better at the cost of a much higher area density of 8.793 kg/m2 , compared to only 3.574 kg/m2 for the sandwich radome. If a tapered sandwich core with an angle-dependent, variable thickness is used, the A-sandwich could also convince with better electromagnetic transparency in the Ka band than the monolithic radome.
