Abstract
The article investigates the scheme of excitation of an electromagnetic field with circular polarization due to crossed strip transmission lines. Two variants are compared: coplanar and microstrip transmission lines that excite circular polarization of the magnetic field in the space above the intersection of strip structures. The degree of ellipticity of the field at the intersection of strip structures can be changed by changing the phase mismatch between exciting oscillation sources. Modeling of these devices in the computer-aided design system made it possible to quantify the amplitudes of the components of the electromagnetic field, from which the ellipticity coefficient was calculated at different values of frequency and phase. The obtained results allow us to determine the conditions necessary for the realization of circular polarization of the magnetic field. The studied structures are planned to be used in an integral design to excite circular polarization oscillations in magnetic micro- and nanostructures.
