A dielectric photonic parabolic reflector

Electromagnetic bandgap antennas and components for microwave and (sub)millimeter wave applications

“…Several antenna configurations using EBG crystals have already been studied to mention but a few: dipole antennas [18], [19], slot antennas, [20], patch antennas [9], [21]- [24], bow-tie antennas [25], spiral and curl antennas [26]- [28], superstrate antennas or resonant cavity antennas [29]- [31], parabolic reflector antennas [32] and combinations of the above [33].…”

Enhancement of Directivity Using 2d-Electromagnetic Crystals Near the Band-Gap Edge: A Full-Wave Approach

“…EBGs are often employed to improve the performances of antennas in the microwave range of frequencies: monopole [10], dipole [11], [12] and wire antennas [13]; slot [14,15] and patch antennas [15][16][17][18]; bow-tie [19], spiral and curl antennas [20]; parabolic reflectors [21]; arrays [22]. In [23], EBG surfaces for effective polarization diversity of wireless communications antenna systems had been optimized using a neural network.…”
