The article considers the problem of electromagnetic wave diffraction on a microstrip frame structure. Its solution obtained using the method of integral equations is described.

A mathematical model of a microstrip loop antenna in the mode of excitation by a plane electromagnetic wave with linear polarization is presented. The incident wave causes the appearance of currents on the radiator, the finding of which is reduced to solving an integral equation. An expression is also presented that describes the integral representation of the field above the radiator, which makes it possible to obtain a picture of the electric field of an electromagnetic wave reflected from the structure.

The numerical result of the calculation of the complex distribution function of the current density at different angles of wave incidence is obtained.

The application of this method makes it possible to accurately calculate the characteristics of such structures in a relatively short time, in comparison with universal analogues.
