  Design of meta-material based two and four port power dividers and magic tee using full mode and half mode substrate integrated waveguide. The area of meta-materials using inter digital capacitors is explored and has been incorporated in the design which exhibits improved performance characteristics. The designed components are fundamental for most of the microwave circuits and exhibit wide range of applications.Software: CST Microwave Studio

  METAMATERIAL BASED ANTENNAS • Investigated the mechanism of incident wave manipulation and surface wave control of metasurfaces and proposed guidelines for integration in antennas. • Experimentally evaluated all the prototypes and verified with the simulation.• The ease in fabrication and integration of the proposed metasurface is highly desirable for compact microwave devices. Software: CST Microwave Studio, ADS, MATLABApplication: • Metasurface integrated low-profile, wideband and high gain antenna (4.15 GHz – 5.85 GHz) • Low-profile and wideband dual-polarized antenna with simple feeding structure (1.69–2.71 GHz)• Low-profile base-station antenna (1.69–2.71 GHz) with stable beamwidth performance • Compact dual-polarized antenna (4.8–6 GHz) with high aperture efficiency targeting MIMO application Show less
