AbstractThe design of substrate integrated waveguide couplers for adaptive receiver applications employing tapered slot antennas is presented. Two different 20 dB couplers are designed on low-permittivity substrate, and their performances are verified by commercially available field solvers. For an incident plane wave, the systems of antenna and couplers are demonstrated to provide the desired operation between 18 GHz and 28 GHz in terms of both received E-field levels and propagation through the components. Antenna radiation patterns are provided. Two different SIW coupler designs are compared with measurements and are found in good agreement, thus validating the design procedure. © 2013 EurAAP.
