The results of researching on the microwave processes in the microstrip antenna in which the substrate is consist of composite structure: ferroelectric – ferromagnetic – dielectric was presented. The paper shows that unified wave can be present in this structure, which combines the properties of electromagnetic and spin types of waves – this is a hybrid electromagnetic-spin wave. The dispersion characteristic of this wave was obtained and its dependence on the applied electric field to the ferroelectric layer was established. This dependence is a consequence of two effects: magnetoelectric effect and dependence dielectric constant from applied electric field. The total effect is a change in the resonant frequency of antenna under study about 2 GHz with the applied electric field changed on 40 kV/cm. It was also found that, depending on the value of the applied electric field, the mode of standing waves can be achieved.
