Abstract:

Modern means of transport, such as aircraft, can contain several dozens transmitting and receiving antennas aboard. Each of these antennas is the potential source of the interference for the others. That is why the developers have to take appropriate steps to decrease the undesirable reciprocal effects. This can be made, for example, by means of the optimal positional relationship, or directional patterns correction, or by means of the various coverings. This work presents a method of the body impedance or covering distribution determination, under which the field of the first antenna is the lowest on the second one. It is based on the well-known asymptotic methods of field determination - Geometrical Theory of Diffraction GTD, Uniform Asymptotic Theory UAT 1 and Ritz method for functional minimization 2.
