Abstract
In this work a new design approach, using genetic algorithm optimization, is proposed to control surface waves (SWs) launched from a substrate-integrated waveguide (SIW) planar horn antenna. In particular, by using genetic algorithm optimization in CST Microwave Studio, simple and printed inclusions, defined by sub-wavelength microstrip patches and positioned near the SIW horn aperture, were optimized for power routing of the TM0 SW mode at K-band frequencies. Also, the new structure demonstrated improved matching and reduced back-radiation as well as SW field culmination along the principal axis of propagation. Results are also compared with and without the sub-wavelength patches. Such an SIW-SWL and technique for SW control can be useful for new planar antennas, novel planar circuits for SW powering routing, and holographic beam forming systems.
