photonic crystal-based horn antenna
transverse electrical mode
FDTD method - Opis:
- In this paper, by modifying defects in a photonic crystal lattice, a two-dimensional photonic crystal horn antenna is designed. The photonic crystal used for this purpose is composed of a hexagonal lattice of circular holes in a dielectric slab. The results of this paper allow us to design a photonic crystal antenna capable of separating TE and TM modes. The designed structure has a very simple design that allows low cost fabrication. The structure is numerically simulated using a finite-difference time-domain (FDTD) method. Its wide bandwidth, its low loss and the ability to transmit waves at a terahertz frequency range are the antenna’s main advantages. The return loss for the frequency range of 180 to 215 THz is from –6.63 to –28.3 dB. Moreover, a 35 THz bandwidth is obtained for this structure.
