Abstract: Possibility of effective radiation transmission from the FET-based log-periodic active antenna into the substrate integrated waveguide (SIW) is investigated. The design providing the power sinking at 15GHz into the planar RO4350B waveguide is considered. Proposed design is modeled using the 3D-TLM method. Electromagnetic energy density in the dielectric substrate is calculated. Numerical results are compared with the experimental data for real active antennas.

Key words: active antenna, efficiency, power sink, integrated waveguide.
