What is Evaluation of Antenna Decoupling if There is an Electromagnetic Shield about?

When creating radio engineering systems, it is necessary to place antennas for different purposes at small distances from each other. Even if the antennas operate in different frequency bands, measures must be taken to ensure the electromagnetic compatibility of radio systems that are connected to these antennas. One of the ways to solve the problem of EMC is the use of special electromagnetic screens. Based on the analysis, a method is proposed for calculating the voltage at the terminals of one of the antennas created by the radiation field of the other antenna, in the presence of a decoupling screen [1]. We assume that the antenna, which is a dipole, is located in a rectangular resonator. The resonator is placed in the center of a metal screen with a width many times greater than the wavelength (Fig. 12.1). From the back of the screen, a flat electromagnetic wave created by another antenna falls perpendicular to it. In order to calculate the amount of isolation between the antennas, it is necessary to determine the induced EMF at the terminals of the dipole.
