Abstract


Airborne antenna radiation characteristics and mutual coupling problem research on the integration of airborne antenna design , the Royal Council and airborne electromagnetic compatibility of electronic systems has very important significance. This paper briefly introduces the basic concepts of UTD , the basic method, and the analysis of wire antenna coupler isolation between antennas calculation method based on the actual reference shape parameters of large passenger aircraft , according to both simplify the structure without losing the main principles of electromagnetic scattering , gives a more simplified mathematical model, and various body parts were given a mathematical formulation. From basic models such as cylindrical, conical and flat starting to discuss in detail a first, second and second-order ray tracing method above . For analytical solution can be given the situation , this paper presents the exact analytical solution ; while for numerical search must use the tracking problem is given a numerical search method is more rapid in the last part of ray tracing is also given the specific method of the shadowing . Prepared a ray tracing and field calculation program , the formation of the antenna radiation pattern containing computer software . After comparison with the relevant literature have proved the correctness of the theory and procedures . Gives the airborne antenna pattern calculation and antenna coupling analysis and results of specific examples , and the results are briefly analyzed .
