Design of microwave planar directional coupler based on Substrate Integrated Waveguide
نویسندگان
چکیده
Planar directional coupler using Substrate Integrated Waveguide technology (SIW) is proposed in this paper. The SIW coupler with tapered microstrip-SIW transitions are integrated on the same substrate. Planar form makes this coupler structure easily integrable in microwave planar circuits. These proposed power dividers can be applied to the design of the beam-forming network for communication system. This structure is designed with Finite Element Method (FEM) using HFSS on a single substrate of ARLON 1000. Simulated results are presented and discussed.
