Abstract

Different techniques are introduced for characterizing EBG structures to design EBG waveguides working in MM frequency band. Two different square and triangle lattices of holes are used to design the EBG waveguides. The width of rectangle lattice waveguide was optimized to increase its bandwidth. An EBG waveguide of 49.1 mm (equivalent to 19 EBG cells) was designed and fabricated. The performance of these EBG waveguides makes them viable alternatives as guiding structure of electromagnetic waves noting better than -10 dB return loss from 27 GHz to 31.5 GHz and insertion loss in the order of 2.5 over the same bandwidth.
