Microwave study of planar honeycomb EBG lattice with hexagonal basis points

Abstract

Hexagonal basis for EBG lattice structures have been reported due to their capability to accommodate maximum numbers of neighbors resulting closed packed array of hexagonal patches ideal for steerable devices for navigation. Present work reports the analysis of hexagonal basis in honeycomb metallo-dielectric lattice structure in Ka band. Hexagonal EBG are designs at λ g /6 wavelength and are fed by microstripline from the back plane. Simulation and experiments shows that the stop band characteristics is observed from 32 GHz to 42 GHz frequency range.
