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.
