Triangular Lattice Dielectric EBG Antenna

A Novel Polarization-Independent, Free-Space, Microwave Beam Splitter Utilizing an Inkjet-Printed, 2-D Array Frequency Selective Surface

“…This could be a 2-D array of dipoles [10], an array of loops linked together with lumped elements [11], stacked arrays of dielectric rods [12], etc. In any configuration, they have the unique property that at a single frequency they act as an infinite impedance surface to plane waves, and at other frequencies they act as transparent surfaces [6].…”

Investigation of Electromagnetic Band-Gap Structures Using Metallic Open Square Rings for Microwave Applications

“…The simulation results showed better than 10 dB return loss performance from 27 GHz to 31.5 GHz with insertion loss of better than 2.5 dB over the same bandwidth, and also high isolation in the range of 20 dB with an adjacent EBG waveguide. In [56], a two-dimensional triangular lattice EBG (TEBG) antenna ( Fig. 2.18) was realized with dielectric rods of length h = 20 mm, radius r = 1.5 mm, and ε r = 37 arranged in a triangular lattice with a = 13 mm.…”
