Multi-Functional Six Ports SIW Microwave Component for X-band Applications

ABSTRACT

A novel symmetric two layer six ports multi-functional microwave component was designed and presented in the present study. The proposed component consists of two 90-degree broadband double layer substrate integrated waveguide couplers and two T-shape power dividers. By exciting each port, the component could act as a −6 dB equal power divider, an unequal −3/−6 dB 90-degree coupler, as well as a −3 dB equal coupler. This component with mentioned conditions covers 23% frequency bandwidth with maximum magnitude and phase error of ±0.5 dB and ±0.6 degree in all bandwidths, respectively.

KEYWORDS:

• Microwave component
• Power divider
• Substrate integrated waveguide (SIW)
• Unequal coupler
